CC -!- FUNCTION: Involved in targeting and insertion of nascent membrane
CC proteins into the cytoplasmic membrane. Acts as a receptor for the
CC complex formed by the signal recognition particle (SRP) and the
CC ribosome-nascent chain (RNC). {ECO:0000256|HAMAP-Rule:MF_00920}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=GTP + H2O = GDP + H(+) + phosphate; Xref=Rhea:RHEA:19669,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:37565,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:58189; EC=3.6.5.4;
CC Evidence={ECO:0000256|ARBA:ARBA00035577, ECO:0000256|HAMAP-
CC Rule:MF_00920};
CC -!- SUBUNIT: Part of the signal recognition particle protein translocation
CC system, which is composed of SRP and FtsY. {ECO:0000256|HAMAP-
CC Rule:MF_00920}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000256|HAMAP-
CC Rule:MF_00920}; Peripheral membrane protein {ECO:0000256|HAMAP-
CC Rule:MF_00920}; Cytoplasmic side {ECO:0000256|HAMAP-Rule:MF_00920}.
CC Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00920}. Membrane
CC {ECO:0000256|ARBA:ARBA00004287}; Peripheral membrane protein
CC {ECO:0000256|ARBA:ARBA00004287}; Cytoplasmic side
CC {ECO:0000256|ARBA:ARBA00004287}.
CC -!- SIMILARITY: Belongs to the GTP-binding SRP family. FtsY subfamily.
