6-pyruvoyltetrahydropterin synthase

6-pyruvoyltetrahydropterin synthase

In enzymology, a 6-pyruvoyltetrahydropterin synthase (EC number|4.2.3.12) is an enzyme that catalyzes the chemical reaction

:6- [(1S,2R)-1,2-dihydroxy-3-triphosphooxypropyl] -7,8-dihydropterin ightleftharpoons 6-pyruvoyl-5,6,7,8-tetrahydropterin + triphosphate

Hence, this enzyme has one substrate, 6- [(1S,2R)-1,2-dihydroxy-3-triphosphooxypropyl] -7,8-dihydropterin, and two products, 6-pyruvoyl-5,6,7,8-tetrahydropterin and triphosphate.

This enzyme belongs to the family of lyases, specifically those carbon-oxygen lyases acting on phosphates. The systematic name of this enzyme class is 6- [(1S,2R)-1,2-dihydroxy-3-triphosphooxypropyl] -7,8-dihydropterin triphosphate-lyase (6-pyruvoyl-5,6,7,8-tetrahydropterin-forming). Other names in common use include 2-amino-4-oxo-6- [(1S,2R)-1,2-dihydroxy-3-triphosphooxypropyl] -7,8-, and dihydroxypteridine triphosphate lyase. This enzyme participates in folate biosynthesis.
