- Abstract
- Uric acid is the end product of the purine degradation pathway in humans. It is catabolized to allantoin by urate oxidase or uricase (E.C. 1.7.3.3.) in most vertebrates except humans, some primates, birds, and certain species of reptiles. Here we provide evidence that mouse transthyretin-related protein facilitates the hydrolysis of 5-hydroxyisourate, the end product of the uricase reaction. Mutagenesis experiments showed that the residues that are absolutely conserved across the TRP family, including His11, Arg51, His102, and the Cterminal Tyr-Arg-Gly-Ser, may constitute the active site of mTRP. Based on these results, we propose that the transthyretin-related proteins present in diverse organisms are not functionally related to transthyretin but actually function as hydroxyisourate hydrolases.
