Spring 2009 Schedule
Invited Speaker
Date: May 13, 12-1pm, Star (Stata D463)
Speaker: Ty Thomson
We will have lunch with Ty Thomson (a SynBERC alum) who will describe a computational
system for modeling BioBrick parts.
Title: A framework for modeling BioBrick parts: Towards the predictable design of synthetic systems
The BioBricks framework was designed to facilitate the easy construction of a diverse array of
synthetic systems by optimizing the modularity and reusability of functional DNA parts.  This is
made possible by a strong adherence to the principle of encapsulation in the design of the
individual BioBricks parts, wherein each component is meant to be functionally independent of the
system in which it is used.  However, there is currently no standard in silico framework for
modeling systems composed of BioBrick parts that also offers this same level of functional
reusability.  I will present a computational framework for modeling BioBrick parts that closely
mirrors the modularity of the parts themselves.  This framework allows for the rapid computational
prototyping of synthetic systems, even by non-modelers, enabling researchers to design, explore,
test and optimize the behavior of synthetic systems prior to their actual construction in the

SynBERC Student Exchange Talk
Date: May 1, 1-2 pm, 34-401 (Grier Room)
Speaker: Jonathan Goler
One of the necessary steps in the advancement of synthetic biology
is a method of producing sensors for myriad biological compounds. In-
Vitro selection (SELEX) of metabolites is a well-established method for
discovering RNA or DNA molecules that specifically bind an arbitrary
metabolite. We examines the dependence on Magnesium on a
selection for a biologically relevant molecule, para-Amino-Phenylalanine.
Since SELEX is typically carried out at 10 mM Mg2+, and cells typically
have approximately 1 mM Mg2+, we sought to know a) whether high-
affinity aptamers could be selected at such low, but biologically relevant
Magnesium levels; and b) whether structures derived from one magnesium
concentration are adaptable to different magnesium concentrations. Thus,
parallel selections were carried out at four magnesium concentrations(1,
2.5, 5 and 10 mM). Each of the four selections succeeded in yielding pAF
binding RNA molecules, and reselection of isolates demonstrated that
molecules could be optimized for different magnesium concentrations, de-
pending on the requirements of the biological application.
SynBERC Distinguished Lecture and Synthetic Biology Working Group Lunch Invited Speaker
Title: Acinetobacter baylyi ADP1 as a chassis for the directed evolution of genes and genomes
Date: April 22, 12-1pm, Kiva (Stata 449)
Speaker: Ichiro Matsumura
We will have lunch with Ichiro Matsumura as he speaks about a new model organism for synthetic
This talk will be webcast to the SynBERC research centers: Berkeley, Stanford, UCSF, and Harvard.
Synthetic biologists generally build upon the Escherichia coli chassis, which usually necessitates
a life of cloning. Acinetobacter baylyi sp. ADP1 offers two significant advantages over E. coli:
natural competence, and efficient homologous recombination. I will explain how these natural
advantages obviate cloning and streamline the directed evolution of genes and genomes.  I will
also describe the engineering of a broad host range expression vector pBAV1K (Biobrick Accepting
Vector) that replicates and produces proteins in a wide variety of gram negative and gram positive
bacteria.  These tools enable the facile laboratory evolution of genes and chromosomes, without 
restriction digests or ligation reactions.

Talk: Adp1: A model organism for Synthetic Biology/TBA
Date April 15, 12-1pm, Kiva
Speaker: Jason Kelly
Talk: Protein domain construction and its relationship to assembly standards
Date: March 18, 12-1pm, 34-401B
Speaker: The discussion will be led by Tom Knight
Protein coding regions containing multiple domains.  We will discuss the construction of
multi-domain  proteins and possible replacements for current assembly strategies to make these
easier to build.  The BBF RFC's for much of this discussion are already online here  in RFC 11,
13, and 14:
A draft version of BBF RFC 15, which uses a new family of parts to add new capabilities to the 
existing BioBrick standard is available here:
Talk: Registry Discussion
Date: February 4th and 11th, 12-1pm, Kiva (Stata 449)
Speakers: Reshma Shetty, Meagan Lizarazo, Barry Canton, and Randy Rettberg.
The Registry has been presented as a "catalog" of biological parts. It has also been referred to as
a collection of poor quality parts. For several months, Reshma and Barry have been converting the
Registry into a better catalog and have been curating the parts. They will present this work.
Spring is the time of the year when many changes are made to the Registry and the iGEM
Randy will describe some of those changes and ask for comments.
Finally, we have described a hierarchy of Systems -> Devices -> Parts.  The Registry has Parts
but does not deal explicitly with Devices. We will present some of our thoughts on how devices
should be represented.
The presentations will be limited to allow for lots of discussion and suggestions.
Invited Speaker: Peter Carr from MIT Media Lab (with Farren Isaacs, Bram Sterling, Harris Wang,
George Church, and Joseph Jacobson)
Talk: Genome Engineering and the Construction of New Genetic Codes
Date:  2/18/09, 12-1pm, G449
Abstract: Our capacity to engineer genetic material is moving beyond the level of single genes to
the scale of genomes. Still, our ability to paint effectively on a canvas as large as a genome is
modest, dwarfed by our growing ability to synthesize DNA, which is in turn dwarfed by our ability
to sequence.
We present the rE. coli project, a collaborative effort to re-engineer the genetic code of E.
coli strain MG1655. The goal of this work is to remove all instances of one type of codon (the
amber stop codon, i.e. TAG) from the genome, replacing them with a synonymous codon (ochre, TAA).
On a practical level, this strain will provide a plug-and-play opportunity for those advancing
work on non-natural amino acid incorporation. It will also be the first step towards generating
an "orthogonal" genetic code, i.e. defining an organism which is unable to make use of exogenous
genetic material. Microorganisms engineered with orthogonal genetic codes would be unable to
utilize antibiotic resistance genes from their environment. In a more distant envisioning, crops
with such a feature would be unable to cross with wild strains.
We will discuss current progress and challenges in engineering at this scale. In particular for
genome-scale design projects, one must consider the two broad categories of failure modes: the 
foreseeable and the unforeseen. Potentially complex interactions between components (some of 
questionable or unknown function) virtually guarantee that not all concerns can be accounted for
at the outset of a project. Robust design modules coupled with flexible troubleshooting
hierarchies are required—we will give examples of these principles applied to the rE. coli work.

Abstract: The subject will be the diversity of computer hacking scenes today, how they got that
way, and what this may tell us about the possible futures of biohacking.  The DIYbio community
is also invited.
Summer/Fall 2008 Schedule: including the Synthetic Biology Lecture Series @ the Synthetic Biology Working Group Lunch
*Invited Speakers: Mikhail Shapiro (MIT,  Biological Engineering) and Vivek Murthy, MD, MBA (Harvard Medical School/Brigham and Women's Hospital)
Talk: Epernicus founders reveal a new social networking site for scientists
Abstract: *Epernicus** is a networking platform for scientists that was created by
researchers at MIT and Harvard.  It helps scientists search efficiently for
specific expertise and people in their real world scientific networks.
Epernicus also makes it easy for researchers to learn about their colleagues
and to stay connected with fellow scientists in their current and past labs,
departments, and institution.

Talk: Looking at chromatin remodeling using Three-Dimensional Electron Microscopy
Abstract: Three-Dimensional Electron Microscopy (3D EM) has emerged as a
powerful technique for structural characterization. Near-atomic resolution
structures of macromolecular assemblies imaged as "single particles" (i.e.
in the absence of a crystalline array) are now being obtained. Arguably one
of 3D EM's most exciting prospects is its potential ability to visualize, at
high resolution and under physiological conditions, the conformational
flexibility central to the function of many macromolecules. I will discuss
the technique and some of the challenges we face to make this prospect a
reality and will illustrate this using examples from our work on the
ATP-dependent chromatin remodeling complex RSC.

*Invited Speaker: J. Keith Joung, M.D., Ph.D. (Harvard Medical School, Pathology; Massachusetts General Hospital, Center for Cancer Research)
Talk: Engineering Zinc Finger Nucleases for Highly Efficient Genome Modification.
Abstract: Zinc finger nucleases are a critical technology for synthetic biology since they can cut,
splice, or tweak genes with high efficiency in a variety of cell types including Drosophila, C.
elegans, plants, and humans. A bottleneck in the application of ZFN technology has been the generation
of highly specific engineered zinc-finger arrays. Dr. Joung's lab has recently described OPEN
(Oligomerized Pool ENgineering), a rapid, publicly available strategy for constructing multifinger
arrays, which is more effective than the previously published modular assembly method. Using OPEN, Dr.
Joung and colleagues have constructed 37 highly active ZFN pairs which induced targeted alterations
with high efficiencies (1%-50%) at 11 different target sites located within three endogenous human
genes (VEGF-A, HoxB13, and CFTR), an endogenous plant gene (tobacco SuRA), and a chromosomally
integrated EGFP reporter gene. OPEN provides an "open-source" method for rapidly engineering highly
active zinc-finger arrays, thereby enabling broader practice, development, and application of ZFN
technology for biological research and gene therapy.
Date: Wednesday, November 5, 2008
Time: 12:00-1:00 pm
Location:  Kiva Seminar Room 32-G449, Stata Center
*Invited Speaker: Edward Boyden, Ph.D.
Talk: Tools for Synthetic Neuroscience and Neurotechnology
Abstract: Our brains and nervous systems mediate everything we perceive, feel, decide, and do--and
act as our ultimate interface to the world. An outstanding challenge for humanity is to understand
these neuromedia interfaces at a level of abstraction that enables us to engineer their
functions--repairing pathology, augmenting cognition, and revealing insights into the human
condition. The Synthetic Neurobiology group invents and applies tools to analyze and engineer brain 
circuits in both humans and model systems. Our current neuroengineering focus is on devising
technologies for controlling the processing within specific neural circuit targets in the brain.
Many of these tools involve "optogenetic" components that sensitize neurons to being controlled
with light. We hope that this synthetic neurobiology approach to the brain will help us better
understand--and engineer improvements upon--the nature of human existence.
