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). Interaction with SRP-RNC leads to the
CC transfer of the RNC complex to the Sec translocase for insertion into
CC the membrane, the hydrolysis of GTP by both Ffh and FtsY, and the
CC dissociation of the SRP-FtsY complex into the individual components.
CC {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. SRP is a ribonucleoprotein
CC composed of Ffh and a 4.5S RNA molecule. {ECO:0000256|HAMAP-
CC Rule:MF_00920}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00920};
CC Peripheral membrane protein {ECO:0000256|HAMAP-Rule:MF_00920};

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.
CC {ECO:0000256|HAMAP-Rule:MF_00920}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
