Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B,C   (OATWY_NEIME | Q93S40)
molecular function
    GO:0050208    polysialic-acid O-acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + an alpha-2,8-linked polymer of sialic acid = CoA + polysialic acid acetylated at O-7 or O-9.
    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.
biological process
    GO:0070207    protein homotrimerization    The formation of a protein homotrimer, a macromolecular structure consisting of three noncovalently associated identical subunits.
