Chain A,B   (GSTA_BPT4 | P04519)
molecular function
    GO:0033820    DNA alpha-glucosyltransferase activity    Catalysis of the transfer of an alpha-D-glucosyl residue from UDP-glucose to a hydroxymethylcytosine residue in DNA.
    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:0016757    transferase activity, transferring glycosyl groups    Catalysis of the transfer of a glycosyl group from one compound (donor) to another (acceptor).
biological process
    GO:0006304    DNA modification    The covalent alteration of one or more nucleotide sites in DNA, resulting in a change in its properties.
    GO:0016032    viral process    A multi-organism process in which a virus is a participant. The other participant is the host. Includes infection of a host cell, replication of the viral genome, and assembly of progeny virus particles. In some cases the viral genetic material may integrate into the host genome and only subsequently, under particular circumstances, 'complete' its life cycle.
