Role of Escherichia coli RpoS, LexA and H-NS global regulators in metabolism and survival under aerobic, phosphate-starvation conditions
Article Abstract:
Research was conducted to examine the role of Escherichia coli RpoS, LexA and H-NS global regulators in metabolism and survival under aerobic, phosphate-starvation conditions. Results provide evidence that E. coli cells starved for phosphate (P(sub i)) under aerobic conditions maintain an active aerobic metabolism for several days, which leads to dramatic changes in the composition of the culture medium. Findings also reveal that H-NS plays an important role in coordinating metabolic and protective processes in P(sub i)-starved cells.

Role of the colicin A lysis protein in the expression of the colicin A operon
Article Abstract:
The role of the cal gene, encoder of the colicin A lysis protein, in the expression of the colicin A operon was investigated. It was found that the cal gene product play a significant role in the the synthesis of the colicin A by Escherichia coli producing cells. Treatment with the antibiotic globomycin during the induction of the colicin A operon confirmed this result.
