molecular function
    GO:0008914    leucyltransferase activity    Catalysis of the reaction: L-leucyl-tRNA + protein = tRNA + L-leucyl-protein.
    GO:0016740    transferase activity    Catalysis of the transfer of a group, e.g. a methyl group, glycosyl group, acyl group, phosphorus-containing, or other groups, from one compound (generally regarded as the donor) to another compound (generally regarded as the acceptor). Transferase is the systematic name for any enzyme of EC class 2.
    GO:0016746    transferase activity, transferring acyl groups    Catalysis of the transfer of an acyl group from one compound (donor) to another (acceptor).
    GO:0016755    transferase activity, transferring amino-acyl groups    Catalysis of the transfer of an amino-acyl group from one compound (donor) to another (acceptor).
biological process
    GO:0030163    protein catabolic process    The chemical reactions and pathways resulting in the breakdown of a protein by the destruction of the native, active configuration, with or without the hydrolysis of peptide bonds.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
