?cl01251: OHCU_decarbox Superfamily (this model, PSSM-Id:412812 is obsolete and has been replaced by 470134)
OHCU decarboxylase The proteins in this family are OHCU decarboxylase - enzymes of the purine catabolism that catalyze the conversion of OHCU into S(+)-allantoin. This is the third step of the conversion of uric acid (a purine derivative) to allantoin. Step one is catalyzed by urate oxidase (pfam01014) and step two is catalyzed by HIUases (pfam00576).
