The purpose of this page is to post the recent articles that we in the Stephanopoulos group review in our nearly-weekly literature review presentations. Sometimes the presenter focuses on a particular paper, and sometimes the roughly one-hour talk gives a brief overview of an important series of related papers.
27 April 2006: Curt Fischer
Curt presented a recent PNAS article  which explicated a newly-discovered operon in E. coli. This operon encodes a previously unreported pathway for uracil degradation, which ends in the excretion of 3-hydroxypropionic acid in the medium. He also briefly mentioned two other recent high-profile papers on nitrogen metabolism--one reported the genome sequence of a anaerobic ammonium oxidizing bacterium and hypthesized the full structure of this metabolic pathway , and the other presents laborious and careful analysis carbon utilization of non-thermophilic archaea living in medium-depth oceanic waters. These bacteria fix inorganic carbon and oxidize nitrogen, and are probably major players in the global nitrogen cycle.

12 Oct 2006: Curt Fischer
Curt presented a very recent paper from Nature Chemical Biology about isotopically instationary analysis of nitrogen assimilation in E. coli. Two notable things about this paper were 1) the invention of a technique for rapid metabolome quenching of E. coli while still obtaining some degree of intracellular/extracellular separation, and 2) the agreement of the measured net fluxes with net fluxes predicted by FBA.

26 Oct 2006: Christine Santos
Christine presented two papers on cannibalism in Bacillus subtilis. In an effort to delay sporulation under conditions of extreme nutrient deprivation, B. subtilis cells with an activated sporulation regulatory protein, Spo0A, make use of two modes of killing to bring about the cell lysis of genetically identical sister cells and the subsequent release of nutrients.

7 February 2008: Curt R. Fischer
Curt discussed the two high-profile papers from the J. Craig Venter Institute on genome transplantation and genome synthesis. The lab debated if the popular press's treatment of the two articles was consistent with their actual scientific impact.

20 March 2008: Mitchell Tai
Mitchell presented a paper on a method for genome-scale analysis and tracking of library population under selective pressure. The technique, named SCALEs, utilizes microarrays to determine distribution of gene fragements in plasmids in a population. It is useful for determining genes which have beneficial (or deleterious) effects on cell fitness.

11 September 2008: Mitchell Tai
Mitchell presented two papers relating to future metabolic engineering tasks for biodiesel production: conversion of fatty acids to fatty acid alkyl esters, and secretion of fatty acids/triglycerides. The former is performed using a wax ester synthase/diglyceride acyltransferase enzyme from Acinetobacter sp. which transesterifies alcohols with acyl-coA. The latter has been found from a knockout of the FAA (acyl-CoA synthetase) enzymes in S. cerevisiae.
