The ompR and envZ genes, which together constitute the ompB operon, are involved in osmoregulatory expression of the OmpF and OmpC proteins, major outer membrane proteins of Escherichia coli. The envZ11 mutation results in the OmpF- OmpC-constitutive phenotype. A mutant which suppressed defects caused by the envZ11 mutation was isolated. The suppressor mutation also suppressed the LamB- PhoA- phenotype caused by the envZ11 mutation. The mutation occurred in the ompR gene and hence was termed ompR77. The ompR77 mutation alone produced no obvious phenotype. Functioning of the ompR77 allele remained envZ gene dependent. Although the ompR77 mutation suppressed the envZ11 mutation, it did not suppress a mutation that occurred in another position within the envZ gene (envZ160). These results indicate that OmpR and EnvZ, two regulatory proteins, functionally interact with each other.
