- Tetrahydroxypteridine cycloisomerase
In
enzymology , a tetrahydroxypteridine cycloisomerase (EC number|5.5.1.3) is anenzyme that catalyzes thechemical reaction :tetrahydroxypteridine xanthine-8-carboxylate
Hence, this enzyme has one substrate,
tetrahydroxypteridine , and one product,xanthine-8-carboxylate .This enzyme belongs to the family of
isomerase s, specifically the class of intramolecularlyase s. The systematic name of this enzyme class is tetrahydroxypteridine lyase (isomerizing). It employs one cofactor,NAD+ .References
