IUBMB Enzyme Nomenclature


Accepted name: ureidoglycolate amidohydrolase

Reaction: (S)-ureidoglycolate + H2O = glyoxylate + 2 NH3 + CO2

Other name(s): ureidoglycolate hydrolase; UAH (gene name)

Systematic name: (S)-ureidoglycolate amidohydrolase (decarboxylating)

Comments: This plant enzyme is involved in the degradation of ureidoglycolate, an intermediate of purine degradation. Not to be confused with EC, ureidoglycolate lyase, which releases urea rather than ammonia.
