Differential levels of fertility inhibition among F-like plasmids are related to the cellular concentration of finO mRNA.

Molecular microbiology - 1 Mar 1992

van Biesen T, Frost L S

Abstract excerpt

The FinOP system of F-like plasmids consists of an antisense RNA (FinP) and a 22 kDa protein (FinO) which act in concert to prevent the translation of TraJ, the positive regulator of the transfer operon. Earlier studies suggested that two different variants of finO were responsible for differential levels of fertility inhibition among F-like plasmids. We have shown that these variations are due to the presence of...
