Chain A   (HUTH_PSEPU | P21310)
molecular function
    GO:0016841    ammonia-lyase activity    Catalysis of the release of ammonia by the cleavage of a carbon-nitrogen bond or the reverse reaction with ammonia as a substrate.
    GO:0003824    catalytic activity    Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic.
    GO:0004397    histidine ammonia-lyase activity    Catalysis of the reaction: L-histidine = urocanate + NH3.
    GO:0016829    lyase activity    Catalysis of the cleavage of C-C, C-O, C-N and other bonds by other means than by hydrolysis or oxidation, or conversely adding a group to a double bond. They differ from other enzymes in that two substrates are involved in one reaction direction, but only one in the other direction. When acting on the single substrate, a molecule is eliminated and this generates either a new double bond or a new ring.
biological process
    GO:0006548    histidine catabolic process    The chemical reactions and pathways resulting in the breakdown of histidine, 2-amino-3-(1H-imidazol-4-yl)propanoic acid.
    GO:0019556    histidine catabolic process to glutamate and formamide    The chemical reactions and pathways resulting in the breakdown of histidine into other compounds, including glutamate and formamide.
    GO:0019557    histidine catabolic process to glutamate and formate    The chemical reactions and pathways resulting in the breakdown of histidine into other compounds, including glutamate and formate.
    GO:0006547    histidine metabolic process    The chemical reactions and pathways involving histidine, 2-amino-3-(1H-imidazol-4-yl)propanoic acid.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
