Summary:
(S)-(+)-allantoin is a common product of purine degradation. E. coli is able to utilize allantoin as the sole source of nitrogen under anaerobic conditions [Cusa99]. Many organisms that degrade (S)-(+)-allantoin do so with the concomitant production of ammonia. Following (S)-(+)-allantoin ring opening by allantoinase, there are two immediate steps in which ammonia is formed - the conversion of allantoate to S-ureidoglycine, and the conversion of the latter to S-ureidoglycolate [Cusa99, Werner10, Serventi10].

Radio-labelled carbon experiments indicated the presence of a uricase that catalyses degradation of urate to S-allantoin, but no such enzyme has been detected in E. coli [Xi00]. However, a pathway of urate degradation to allantoin I has been discovered in other organisms.

Superpathways: allantoin degradation IV (anaerobic) , allantoin degradation to glyoxylate III
