physiological function
conversion of allantoin to allantoate is the second of the two ring-opening steps in purine utilization
physiological function
mechanism of racemization involves residue Glu78 acting as a base for the abstraction of the C5 proton of (S)-allantoin and Cys 180 transferring a proton on the opposite side of the allantoin ring. In the stereoinversion of (R)-allantoin, proton abstraction is performed by Cys 180 and reprotonation by Glu 78
