Abstract
Escherichia coli bulk protein synthesis continued during the first 3–4 h of carbon starvation at 50–75% that of non-starved (growing) cells. Two-dimensional gel electrophoresis analysis of in vivo pulse-labelled proteins resolved at least 30 polypeptides with new or increased synthesis, relative to total protein synthesis, during this time. Among these polypeptides were several that were also synthesized by ethanol-treatedE. coli (heat-shock proteins). In addition, a number of unique polypeptides were synthesized by carbon-starved cells. These ‘starvation proteins’ may be involved in survival of the starving bacteria.This publication has 10 references indexed in Scilit:
