Supplementation of growth media with high concentrations of substances like sucrose results in the induction of OmpC synthesis and the suppression of OmpF synthesis. We isolated a novel mutant in which OmpF synthesis is in the opposite direction from normal osmoregulation. By transductional mapping, the mutation was localized at 75 min between malA and aroB on the Escherichia coli chromosome map where the ompR-envZ region is. The mutation was suppressed by a plasmid carrying the ompR gene but not by a plasmid carrying the envZ gene alone. The mutation also resulted in the almost complete suppression of OmpC synthesis. However, the remaining OmpC synthesis was osmoregulated normally. Based on these observations, the mechanism of osmoregulation of OmpF-OmpC synthesis is discussed.

Mutation causing reverse osmoregulation of synthesis of OmpF, a major outer membrane protein of Escherichia coli
