Enzyme Function FUNCTION: An anti-sigma factor for extracytoplasmic function (ECF) sigma factor sigma-E (RpoE). ECF sigma factors are held in an inactive form by an anti-sigma factor until released by regulated intramembrane proteolysis (RIP). RIP occurs when an extracytoplasmic signal triggers a concerted proteolytic cascade to transmit information and elicit cellular responses. The membrane-spanning regulatory substrate protein is first cut periplasmically (site-1 protease, S1P, DegS), then within the membrane itself (site-2 protease, S2P, RseP), while cytoplasmic proteases finish degrading the anti-sigma factor, liberating sigma-E (By similarity). {ECO:0000250}.

Induction
Subcellular Location SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}. Note=Following cleavage by DegS the large fragment of the protein is still in the inner membrane and retains its anti-sigma-E activity. {ECO:0000250}.
Modified Residue
Post Translational Modification PTM: Sequentially cleaved by DegS (a site-1 protease) in its periplasmic domain between Val-148 and Ser-149, then by RseP (a site-2 protease) between positions Ala-108 and Cys-109. The N-terminal fragment is then degraded by primarily ClpX-ClpP in an ATP-dependent fashion. Sequential cleavage by DegS, RseP and ClpX-ClpP frees RpoE from RseA (By similarity). {ECO:0000250}.
