Abstract
The recombinant expression of proteins has been the method of choice to meet the demands from proteomics and structural genomics studies. Despite its successful production of many heterologous proteins, Escherichia coli failed to produce many other proteins in their native forms. This may be related to the fact that the stresses resulting from the overproduction interfere with cellular processes. To better understand the physiological change during the overproduction phase, we profiled the metabolites along the time course of the recombinant protein expression. We identified 32 metabolites collected from different time points in the protein production phase. The stress induced by protein production can be characterized by (A) the increased usage of aspartic acid, choline, glycerol, and N-acetyllysine; and (B) the accumulation of adenosine, alanine, oxidized glutathione, glycine, N-acetylputrescine, and uracil. We envision that this work can be used to create a strategy for the production of usable proteins in large quantities.

High-yield Escherichia coli-based cell-free expression of human proteins
Abstract Production of sufficient amounts of human proteins is a frequent bottleneck in structural biology. Here we describe an Escherichia coli-based cell-free system which yields mg-quantities of human proteins in N-terminal fusion constructs with the GB1 domain, which show significantly increased translation efficiency. A newly generated E. coli BL21 (DE3) RIPL-Star strain was used, which contains a variant RNase E with reduced activity and an excess of rare-codon tRNAs, and is devoid of lon and ompT protease...
