Definition
Catalysis of the reaction: (S)-ureidoglycolate + H(2)O + 2 H(+) = CO(2) + glyoxylate + 2 NH(4)(+)
Comment
Take care to annotate to the reaction, not simply the enzyme name. The name "ureidoglycolate hydrolase" has variously been used to refer to two distinctly different enzymes. Both enzymes act on ureidoglycolate and produce glyoxylate, but the mechanism and reaction products are different. The "ureidoglycolate hydrolase" listed in the Enzyme commission (EC) is a ureidoglycolate amidohydrolase, releasing ammonia, (EC:3.5.3.19, GO:0004848). The "ureidoglycolate hydrolase" characterized in PMID:3915539 (published prior to the EC designation of EC:3.5.3.19) is a ureidoglycolate lyase, releasing urea (EC:4.3.2.3, GO:0050385). The inappropriate labelling of ureidoglycolate lyase as EC:3.5.3.19 has caused much confusion in the literature (see PMID:24107613). Take care to correctly annotate based on the reaction products, rather than name.
