Flk prevents premature secretion of the anti-sigma factor FlgM into the periplasm.

Molecular microbiology - 1 May 2006

Aldridge Phillip, Karlinsey Joyce E, Becker Eric, Chevance Fabienne F V, Hughes Kelly T

Abstract excerpt

The flk locus of Salmonella typhimurium was identified as a regulator of flagellar gene expression in strains defective in P- and l-ring formation. Flk acts as a regulator of flagellar gene expression by modulating the protein levels of the anti-sigma28 factor FlgM. Evidence is presented which suggests that Flk is a cytoplasmic-facing protein anchored to the inner membrane by a single, C-terminal...
