OmpC -OmpF PORIN PROTEINS EXPRESSION OF Escherichia coli IN NUTRIENT BROTH AND THE ROLE OF EnvZ, OmpR, H-NS, AcP AND RpoS ON THIS EXPRESSION

Öz

Although OmpC and OmpF porin proteins have important role to play in the survival of Escherichia coli under different environmental conditions, mechanisms and the influence of different environmental conditions on porin expression is not as well known. In this study, we tried to investigate the role of EnvZ, OmpR, H-NS, AcP and RpoS molecules on control of E. coli OmpC and OmpF porin expression to grown in nutrient broth as a rich medium. It were determined that E. coli strains carrying mutations in the envZ, ompR, rpoS, pta and hns genes showed not significant difference according to wild type point of view grown at nutrient broth. During grown in nutrient broth, While wild type E. coli OmpC expression was increased, OmpF expression was greatly reduced. It were determined that especially increased OmpF porin expression in rpoS mutant E. coli and OmpC porin expression in pta mutant E. coli according to wild type E. coli. There was no expression of ompC and ompF in the ompR mutant. The expression of ompC and ompF in the hns mutant was inconsiderably increased compared to the wild type E. coli.
