CC -!- FUNCTION: Part of the MsrPQ system that repairs oxidized periplasmic
CC proteins containing methionine sulfoxide residues (Met-O), using
CC respiratory chain electrons. Thus protects these proteins from
CC oxidative-stress damage caused by reactive species of oxygen and
CC chlorine generated by the host defense mechanisms. MsrPQ is essential
CC for the maintenance of envelope integrity under bleach stress, rescuing
CC a wide series of structurally unrelated periplasmic proteins from
CC methionine oxidation. The catalytic subunit MsrP is non-stereospecific,
CC being able to reduce both (R-) and (S-) diastereoisomers of methionine
CC sulfoxide. {ECO:0000255|HAMAP-Rule:MF_01206}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=a quinone + H2O + L-methionyl-[protein] = a quinol + L-
CC methionyl-(S)-S-oxide-[protein]; Xref=Rhea:RHEA:51292, Rhea:RHEA-

CC -!- COFACTOR:
CC Name=Mo-molybdopterin; Xref=ChEBI:CHEBI:71302;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_01206};
CC Note=Binds 1 Mo-molybdopterin (Mo-MPT) cofactor per subunit.
CC {ECO:0000255|HAMAP-Rule:MF_01206};
CC -!- SUBUNIT: Heterodimer of a catalytic subunit (MsrP) and a heme-binding
CC subunit (MsrQ). {ECO:0000255|HAMAP-Rule:MF_01206}.
CC -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000255|HAMAP-Rule:MF_01206}.
CC Note=Is attached to the inner membrane when interacting with the MsrQ
CC subunit. {ECO:0000255|HAMAP-Rule:MF_01206}.
CC -!- PTM: Predicted to be exported by the Tat system. The position of the
CC signal peptide cleavage has not been experimentally proven.
CC {ECO:0000255|HAMAP-Rule:MF_01206}.
CC -!- SIMILARITY: Belongs to the MsrP family. {ECO:0000255|HAMAP-
CC Rule:MF_01206}.
