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
