Öz

OmpC ve OmpF porin proteinlerinin farklı çevresel şartlarda Escherichia coli’nin yaşamında önemli bir rol oynamasına rağmen sentezi üzerine farklı çevresel şartların etkisi ve mekanizması henüz tam olarak bilinmemektedir. Bu çalışmada zengin besiyeri olarak nutrient brot besiyerinde üretilen E. coli’nin OmpC ve OmpF porin sentez düzeyi ve bu sentezin kontrolünde EnvZ, OmpR, H-NS, AcP ve RpoS’nin rolü araştırılmıştır. E. coli’nin envZ, ompR, hns, pta ve rpoS gen bölgelerinin mutasyona uğratılmasının besiyerinde üreme açısından yabani tipe göre bir değişim göstermediği belirlenmiştir. Protein sentezinde ise üreme süresince OmpC sentezi artarken, OmpF sentezi oldukça azalmıştır. Yabani tip E. coli’ye göre özellikle rpoS mutantında OmpF, pta mutantında ise OmpC nin oldukça yüksek olduğu tespit edilmiştir. EnvZ’nin porin sentezi için oldukça önemli olduğu, OmpR’nin olmadığı durumda sentezin gerçekleşmediği belirlenmiştir. hns mutasyonunda ise OmpC ve OmpF sentezinin hafifçe arttığı belirlenmiştir.

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

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.
