CC -!- FUNCTION: Involved in targeting and insertion of nascent membrane
CC proteins into the cytoplasmic membrane. Binds to the hydrophobic signal
CC sequence of the ribosome-nascent chain (RNC) as it emerges from the
CC ribosomes. The SRP-RNC complex is then targeted to the cytoplasmic
CC membrane where it interacts with the SRP receptor FtsY.
CC {ECO:0000256|HAMAP-Rule:MF_00306}.
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_00306};
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_00306}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00306}.
CC Note=The SRP-RNC complex is targeted to the cytoplasmic membrane.
CC {ECO:0000256|HAMAP-Rule:MF_00306}.
CC -!- DOMAIN: Composed of three domains: the N-terminal N domain, which is
CC responsible for interactions with the ribosome, the central G domain,
CC which binds GTP, and the C-terminal M domain, which binds the RNA and
CC the signal sequence of the RNC. {ECO:0000256|HAMAP-Rule:MF_00306}.
CC -!- SIMILARITY: Belongs to the GTP-binding SRP family. SRP54 subfamily.
CC {ECO:0000256|ARBA:ARBA00005450, ECO:0000256|HAMAP-Rule:MF_00306}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
