Paul Jaschke

Bio

I am now a Lecturer (equivalent of Assistant Professor) of Synthetic Biology in the Department of Chemistry and Biomolecular Sciences at Macquarie University in Sydney, Australia.

Jaschke Lab @ Macquarie University

I started off my science career at the University of Alberta (Canada), working in the Casey and Michalak labs. Summer student work in the Casey Lab on the human sodium-bicarbonate co-transporter protein resulted in an authorship in a peer-reviewed publication. My honors project in the Michalak Lab had me determining the role of calcium signaling and calreticulin on murine embryonic stem cell differentiation. After achieving a B.Sc. (Honors) in Biochemistry in 2003 I went to the Beatty Lab at the University of British Columbia to start my Ph.D. While at UBC I discovered that a photosynthetic organism called Rhodobacter sphaeroides was capable of re-routing its chlorophyll biosynthetic machinery around a blockage to generate a new type of chlorophyll. November 2010 I was conferred a Ph.D in Microbiology and Immunology from UBC.

I was a post-doc in Drew Endy's lab at Stanford University from Nov 2010 - June 2015. The focus of my project was on redesign phage using both rational and combinatorial methods in order to finish the genetics of a simple system. In December 2012 we published the first report of a fully decompressed genome, using the bacteriophage øX174 as a model. This virus has shared many other firsts in the world of genomics and synthetic biology from being the first DNA genome sequenced by Frederick Sanger to the subject of claims of creating life in a test tube by watchers of Arthur Kornberg and Craig Venter et al.

Work

The Jaschke Lab bridges the fields of Synthetic Biology, Microbiology, Virology, and Systems Biology to answer fundamental questions of:
(1) how to discover all the components necessary to make a functional genome?
(2) how to reconfigure these components to make engineered genomes more reliable and predictable?
(3) how to engineer biology to benefit human health and reduce impacts on our environment?

We aim to answer important questions by pioneering the science and engineering of synthetic genomes by designing, building, testing, and learning from our designs.

My unsuccessful cover illustration submission for JBC paper. A novel Zn-bacteriochlorophyll pathway operates in a Mg-chelatase mutant of Rhodobacter sphaeroides. The bchD mutant cannot chelate Mg2+ into protoporphyrin IX, which instead, has both both Fe2+ (red sphere) and Zn2+ (green sphere) inserted by ferrochelatase. Zn-protoporphyrin IX joins the bacteriochlorophyll pathway and is converted to Zn-bacteriochlorophyll.
