Expression of the major outer-membrane porins in Escherichia coli is transcriptionally controlled during nutrient limitation. Expression of ompF was more than 40-fold higher under glucose limitation than under nitrogen (ammonia) limitation in chemostat cultures at the same growth rate. In contrast, ompC expression was higher under N limitation. The basis of regulation by nutrient limitation was investigated using mutations affecting expression of porin genes. The influence of cyaA, rpoS, ackA… CONTINUE READING
