Abstract
We examined the effects of hydrostatic pressure on the synthesis of Escherichia coli outer membrane proteins, particularly for the osmoregulated ImpC and OmpF porins. It was found that the expression of ompC and ompF was markedly reduced during the growth at high pressure, most likely at the transcriptional level. However, the signal transduction processes through the regulatory proteins, EnvZ and OmpR, was not influenced by the environmental pressure. It was also found that the expression of a presumed novel outer membrane protein, named OmpX, was affected by both the medium osmolarity and pressure in a manner independent of the function of EnvZ and OmpR.Keywords
