Chain A   (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:0048500    signal recognition particle    A complex of protein and RNA which facilitates translocation of proteins across membranes.
