Chain A,C (SRP54_ECOLI | P0AGD7)

molecular function
	GO:0008312	7S RNA binding	Interacting selectively and non-covalently with 7S RNA, the RNA component of the signal recognition particle (SRP).
	GO:0005525	GTP binding	Interacting selectively and non-covalently with GTP, guanosine triphosphate.
	GO:0003924	GTPase activity	Catalysis of the reaction: GTP + H2O = GDP + phosphate.
	GO:0003723	RNA binding	Interacting selectively and non-covalently with an RNA molecule or a portion thereof.
	GO:0000166	nucleotide binding	Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose.
biological process
	GO:0006614	SRP-dependent cotranslational protein targeting to membrane	The targeting of proteins to a membrane that occurs during translation and is dependent upon two key components, the signal-recognition particle (SRP) and the SRP receptor. SRP is a cytosolic particle that transiently binds to the endoplasmic reticulum (ER) signal sequence in a nascent protein, to the large ribosomal unit, and to the SRP receptor in the ER membrane.
	GO:0006612	protein targeting to membrane	The process of directing proteins towards a membrane, usually using signals contained within the protein.
cellular component
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
	GO:0030529	intracellular ribonucleoprotein complex	An intracellular macromolecular complex containing both protein and RNA molecules.
	GO:0048500	signal recognition particle	A complex of protein and RNA which facilitates translocation of proteins across membranes.

	GO:0031226	intrinsic component of plasma membrane	The component of the plasma membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.
	GO:0016020	membrane	A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
	GO:0005886	plasma membrane	The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
