Chain A,B   (AAC2_MYCTO | P9WQG8)
molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    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).
biological process
    GO:0046677    response to antibiotic    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.

Chain A,B   (AAC2_MYCTU | P9WQG9)
molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    GO:0047921    aminoglycoside 2'-N-acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + gentamicin C(1a) = N(2')-acetylgentamicin C(1a) + CoA + H(+). This is acetylation of the 2'-amino group of the 6-deoxy-6-aminoglucose ring.
    GO:0034069    aminoglycoside N-acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + aminoglycoside = CoA + N-acetylaminoglycoside.
    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).
biological process
    GO:0030649    aminoglycoside antibiotic catabolic process    The chemical reactions and pathways resulting in the breakdown of an aminoglycoside antibiotic, any member of a group of broad spectrum antibiotics, of similar toxicity and pharmacology, that contain an aminodeoxysugar, an amino- or guanidino-substituted inositol ring, and one or more residues of other sugars. The group includes streptomycin, neomycin, framycetin, kanamycin, paromomycin, and gentamicin.
    GO:0046677    response to antibiotic    Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.
cellular component
    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.
