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 18.104.22.168, ureidoglycolate lyase, which releases urea rather than ammonia.
