Accepted name: N-malonylurea hydrolase
Reaction: 3-oxo-3-ureidopropanoate + H2O = malonate + urea
Other name(s): ureidomalonase
Systematic name: 3-oxo-3-ureidopropanoate amidohydrolase (urea- and malonate-forming)
Comments: Forms part of the oxidative pyrimidine-degrading pathway in some microorganisms, along with EC (uracil/thymine dehydrogenase) and EC (barbiturase).
