Asymmetric Unit(hide GO term definitions)
Chain A,B   (DNAT_DROME | Q94521)
molecular function
    GO:0008080    N-acetyltransferase activity    Catalysis of the transfer of an acetyl group to a nitrogen atom on the acceptor molecule.
    GO:0004059    aralkylamine N-acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + an aralkylamine = CoA + an N-acetylaralkylamine.
    GO:0004060    arylamine N-acetyltransferase activity    Catalysis of the reaction: acetyl-CoA + an arylamine = CoA + an N-acetylarylamine.
    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:0006584    catecholamine metabolic process    The chemical reactions and pathways involving any of a group of physiologically important biogenic amines that possess a catechol (3,4-dihydroxyphenyl) nucleus and are derivatives of 3,4-dihydroxyphenylethylamine.
    GO:0048066    developmental pigmentation    The developmental process that results in the deposition of coloring matter in an organism, tissue or cell.
    GO:0042420    dopamine catabolic process    The chemical reactions and pathways resulting in the breakdown of dopamine, a catecholamine neurotransmitter and a metabolic precursor of noradrenaline and adrenaline.
    GO:0030187    melatonin biosynthetic process    The chemical reactions and pathways resulting in the formation of melatonin (N-acetyl-5-methoxytryptamine).
    GO:0046334    octopamine catabolic process    The chemical reactions and pathways resulting in the breakdown of octopamine, 1-(p-hydroxyphenyl)-2-aminoethanol. The D enantiomer is about one-tenth as active as norepinephrine and is found in the salivary glands of Octopus and Eledone species.
    GO:0045187    regulation of circadian sleep/wake cycle, sleep    Any process that modulates the frequency, rate or extent of sleep; a readily reversible state of reduced awareness and metabolic activity that occurs periodically in many animals.
    GO:0042429    serotonin catabolic process    The chemical reactions and pathways resulting in the breakdown of serotonin (5-hydroxytryptamine), a monoamine neurotransmitter occurring in the peripheral and central nervous systems, also having hormonal properties.
    GO:0030431    sleep    Any process in which an organism enters and maintains a periodic, readily reversible state of reduced awareness and metabolic activity. Usually accompanied by physical relaxation, the onset of sleep in humans and other mammals is marked by a change in the electrical activity of the brain.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
