CC -!- FUNCTION: A probable intramembrane site-2 protease (S2P) that cleaves
CC type-2 transmembrane proteins within their membrane-spanning domains.
CC Cleaves PbpB (PBP3, FtsI) near 'Ala-102' and 'Ala-103' in response to
CC oxidative stress; cleavage is inhibited by Wag31-PbpB interaction.
CC Probably also cleaves anti-sigma factors RskA, RslA and RsmA but not
CC RsdA. {ECO:0000250}.
CC -!- FUNCTION: Regulated intramembrane proteolysis (RIP) occurs when an
CC extracytoplasmic signal (possibly oxidative stress) triggers a
CC concerted proteolytic cascade to transmit information and elicit
CC cellular responses. The membrane-spanning regulatory substrate protein
CC (includes anti-sigma factors RskA, RslA, RsmA, and PbpB in
CC M.tuberculosis) is first cut extracytoplasmically (site-1 protease,
CC S1P), then within the membrane itself (site-2 protease, S2P, this
CC entry), while cytoplasmic proteases finish degrading the regulatory
CC protein, liberating the effector protein (ECF sigma factors SigK, SigL
CC and SigM) (By similarity). {ECO:0000250}.
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105; Evidence={ECO:0000250};
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the peptidase M50B family. {ECO:0000305}.
