Chain A,B,C,D   (HUTU_BACSU | P25503)
molecular function
    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.
    GO:0016153    urocanate hydratase activity    Catalysis of the reaction: 4-imidazolone-5-propanoate + H(+) = trans-urocanate + H(2)O.
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.
