CC   -!- FUNCTION: Part of the ABC transporter complex MetNIQ involved in
CC       methionine import. Responsible for energy coupling to the transport
CC       system. {ECO:0000255|HAMAP-Rule:MF_01719}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + H2O + L-methionine(out) = ADP + H(+) + L-methionine(in)
CC         + phosphate; Xref=Rhea:RHEA:29779, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01719};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + D-methionine(out) + H2O = ADP + D-methionine(in) + H(+)
CC         + phosphate; Xref=Rhea:RHEA:29767, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,

CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01719};
CC   -!- SUBUNIT: The complex is composed of two ATP-binding proteins (MetN),
CC       two transmembrane proteins (MetI) and a solute-binding protein (MetQ).
CC       {ECO:0000255|HAMAP-Rule:MF_01719}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_01719};
CC       Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_01719}.
CC   -!- SIMILARITY: Belongs to the ABC transporter superfamily. Methionine
CC       importer (TC 3.A.1.24) family. {ECO:0000255|HAMAP-Rule:MF_01719}.
