CC   -!- FUNCTION: Hydrolyzes ureidoacrylate to form aminoacrylate and
CC       carbamate. The carbamate hydrolyzes spontaneously, thereby releasing
CC       one of the nitrogen atoms of the pyrimidine ring as ammonia and one of
CC       its carbon atoms as CO2. {ECO:0000255|HAMAP-Rule:MF_00830}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(Z)-3-ureidoacrylate + H(+) + H2O = (Z)-3-aminoacrylate + CO2
CC         + NH4(+); Xref=Rhea:RHEA:42624, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC         methylaminoacrylate + CO2 + NH4(+); Xref=Rhea:RHEA:42620,

CC         EC=3.5.1.110; Evidence={ECO:0000255|HAMAP-Rule:MF_00830};
CC   -!- INDUCTION: Up-regulated by the nitrogen regulatory protein C (NtrC also
CC       called GlnG) and repressed by RutR. {ECO:0000255|HAMAP-Rule:MF_00830}.
CC   -!- SIMILARITY: Belongs to the isochorismatase family. RutB subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00830}.
