Allophanate hydrolase catalyzes the second reaction in an ATP-dependent two-step degradation of urea to ammonia and C02, following the action of the biotin-containing urea carboxylase. The yeast enzyme, a fusion of allophanate hydrolase to urea carboxylase, is designated urea amidolyase. [Central intermediary metabolism, Nitrogen metabolism]
