CC -!- FUNCTION: Involved in the anaerobic nitrogen utilization via the
CC assimilation of allantoin (PubMed:10601204, PubMed:20038185). Catalyzes
CC specifically the hydrolysis of allantoate to yield CO2, NH3 and S-
CC ureidoglycine, which is unstable and readily undergoes a second
CC deamination by S-ureidoglycine aminohydrolase AllE to yield S-
CC ureidoglycolate and NH3 (PubMed:20038185). In vivo, the spontaneous
CC release of S-ureidoglycolate and ammonia from S-ureidoglycine appears
CC to be too slow to sustain an efficient flux of nitrogen
CC (PubMed:20038185). {ECO:0000269|PubMed:10601204,
CC ECO:0000269|PubMed:20038185}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=allantoate + 2 H(+) + H2O = (S)-2-ureidoglycine + CO2 +
CC NH4(+); Xref=Rhea:RHEA:27485, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16526, ChEBI:CHEBI:17536, ChEBI:CHEBI:28938,
CC ChEBI:CHEBI:59947; EC=3.5.3.9;
CC Evidence={ECO:0000269|PubMed:20038185};
CC -!- COFACTOR:
CC Name=Zn(2+); Xref=ChEBI:CHEBI:29105;
CC Evidence={ECO:0000269|PubMed:17362992};
CC Note=Binds 2 Zn(2+) ions per subunit (PubMed:17362992). Also able to
CC bind Mn(2+) (PubMed:25020232). {ECO:0000269|PubMed:17362992,
CC ECO:0000269|PubMed:25020232};
CC -!- ACTIVITY REGULATION: Sulfate could be an allosteric effector of the
CC enzyme that is responsible for stabilizing substrate binding. In
CC addition, this anion effector may act as a counterion during enzyme-
CC mediated catalysis. {ECO:0000305|PubMed:17362992}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC pH dependence:
CC Optimum pH is 8. Less active under acidic conditions.
CC {ECO:0000305|PubMed:17362992};
CC -!- PATHWAY: Nitrogen metabolism; (S)-allantoin degradation.
CC {ECO:0000305|PubMed:10601204}.
CC -!- SUBUNIT: Homodimer. {ECO:0000269|PubMed:17362992}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- INDUCTION: By glyoxylate and allantoin under anaerobic conditions.
CC {ECO:0000269|PubMed:10601204}.
CC -!- SIMILARITY: Belongs to the peptidase M20 family. {ECO:0000305}.
