Degradation of FinP antisense RNA from F-like plasmids: the RNA-binding protein, FinO, protects FinP from ribonuclease E.

Abstract excerpt

Transfer of F-like plasmids is regulated by the FinOP system, which controls the expression of traJ, a positive regulator of the transfer operon. F FinP is a 79 base antisense RNA, composed of two stem-loops, complementary to the 5' untranslated leader of traJ mRNA. Binding of FinP to the traJ leader sequesters the traJ ribosome binding site, preventing its translation and repressing plasmid transfer. The FinO...
