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. MsrQ provides electrons for reduction to the
CC reductase catalytic subunit MsrP, using the quinone pool of the
CC respiratory chain. {ECO:0000256|HAMAP-Rule:MF_01207}.
CC -!- COFACTOR:
CC Name=FMN; Xref=ChEBI:CHEBI:58210;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01207};
CC Note=Binds 1 FMN per subunit. {ECO:0000256|HAMAP-Rule:MF_01207};
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01207};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000256|HAMAP-Rule:MF_01207};
CC -!- SUBUNIT: Heterodimer of a catalytic subunit (MsrP) and a heme-binding
CC subunit (MsrQ). {ECO:0000256|HAMAP-Rule:MF_01207}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_01207};
CC Multi-pass membrane protein {ECO:0000256|HAMAP-Rule:MF_01207}. Membrane
CC {ECO:0000256|ARBA:ARBA00004141}; Multi-pass membrane protein
CC {ECO:0000256|ARBA:ARBA00004141}.
CC -!- SIMILARITY: Belongs to the MsrQ family. {ECO:0000256|HAMAP-
CC Rule:MF_01207}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_01207}.
