Asymmetric/Biological Unit(hide GO term definitions)
Chain A,B,C,D   (ALLB_ECOLI | P77671)
molecular function
    GO:0004038    allantoinase activity    Catalysis of the reaction: allantoin + H2O = allantoate.
    GO:0050897    cobalt ion binding    Interacting selectively and non-covalently with a cobalt (Co) ion.
    GO:0016787    hydrolase activity    Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3.
    GO:0016810    hydrolase activity, acting on carbon-nitrogen (but not peptide) bonds    Catalysis of the hydrolysis of any carbon-nitrogen bond, C-N, with the exception of peptide bonds.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0009442    allantoin assimilation pathway    The pathways by which allantoin is processed and converted to ureidoglycolate, and then into metabolically useful substrates. E. coli are able to utilize allantoin as a sole nitrogen source under anaerobic conditions by converting it to ureidoglycolate; this may be further metabolized to produce glyoxylate and thence 3-phosphoglycerate, or alternatively oxidized to oxolureate, which can converted into oxamate and carbamoylphosphate. This may then be further metabolized to CO2, NH4+ and ATP.
    GO:0000256    allantoin catabolic process    The chemical reactions and pathways resulting in the breakdown of allantoin, (2,5-dioxo-4-imidazolidinyl)urea.
    GO:0006144    purine nucleobase metabolic process    The chemical reactions and pathways involving purine nucleobases, one of the two classes of nitrogen-containing ring compounds found in DNA and RNA, which include adenine and guanine.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
