Beta-ureidopropionase
From Wikipedia, the free encyclopedia
In enzymology, a beta-ureidopropionase (EC 3.5.1.6) is an enzyme that catalyzes the chemical reaction
- N-carbamoyl-beta-alanine + H2O
beta-alanine + CO2 + NH3
Thus, the two substrates of this enzyme are N-carbamoyl-beta-alanine and H2O, whereas its 3 products are beta-alanine, CO2, and NH3.
This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N-carbamoyl-beta-alanine amidohydrolase. This enzyme participates in 3 metabolic pathways: pyrimidine metabolism, beta-alanine metabolism, and pantothenate and coa biosynthesis.
