Supporting evidence for this pathway in Arabidopsis: This is a superpathway composed of one or more sub-pathways that may have different levels of evidence. All of its sub-pathways have been accepted for this species using SAVI v.1.0 [more info] Summary from MetaCyc: The purine degradation pathway plays an important role in nitrogen metabolism in most organisms. The final product of de novo purine biosynthesis, inosine-5'-phosphate, is degraded through sequential enzymatic steps into urate, which contains a high level of nitrogen (see purine nucleotides degradation I (plants)). In most organisms, including some bacteria, plants, and certain animals, urate is metabolized via a common pathway, producing the stereospecific form S-allantoin as the final product . Some organisms that are not able to degrade urate include humans, apes, birds and reptiles . Finally, S-allantoin is degraded to glyoxylate in a route that regenerates the nitrogen in the form of ammonia. glyoxylate enters central metabolism.
