DE RecName: Full=Signal recognition particle protein; DE AltName: Full=Fifty-four homolog; GN Name=ffh; OS Mycoplasma mycoides subsp. mycoides SC (strain PG1). OC Bacteria; Tenericutes; Mollicutes; Mycoplasmataceae; Mycoplasma. OX NCBI_TaxID=272632; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=PG1; RX PubMed=14762060; DOI=10.1101/gr.1673304; RA Westberg J., Persson A., Holmberg A., Goesmann A., Lundeberg J., RA Johansson K.-E., Pettersson B., Uhlen M.; RT "The genome sequence of Mycoplasma mycoides subsp. mycoides SC type RT strain PG1T, the causative agent of contagious bovine pleuropneumonia RT (CBPP)."; RL Genome Res. 14:221-227(2004). CC -!- FUNCTION: Involved in targeting and insertion of nascent membrane CC proteins into the cytoplasmic membrane. Binds to the hydrophobic CC signal sequence of the ribosome-nascent chain (RNC) as it emerges CC from the ribosomes. The SRP-RNC complex is then targeted to the CC cytoplasmic membrane where it interacts with the SRP receptor FtsY CC (By similarity). CC -!- SUBUNIT: Part of the signal recognition particle protein CC translocation system, which is composed of SRP and FtsY (By CC similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm. Note=The SRP-RNC complex is CC targeted to the cytoplasmic membrane (By similarity). CC -!- DOMAIN: Composed of three domains: the N-terminal N domain, which CC is responsible for interactions with the ribosome, the central G CC domain, which binds GTP, and the C-terminal M domain, which binds CC the RNA and the signal sequence of the RNC (By similarity). CC -!- SIMILARITY: Belongs to the GTP-binding SRP family. SRP54 CC subfamily.
