- Quinate dehydrogenase (pyrroloquinoline-quinone)
In
enzymology , a quinate dehydrogenase (pyrroloquinoline-quinone) (EC number|1.1.99.25) is anenzyme that catalyzes thechemical reaction :quinate + pyrroloquinoline-quinone ightleftharpoons 3-dehydroquinate + reduced pyrroloquinoline-quinone
Thus, the two substrates of this enzyme are
quinate andpyrroloquinoline-quinone , whereas its two products are3-dehydroquinate andreduced pyrroloquinoline-quinone .This enzyme belongs to the family of
oxidoreductase s, specifically those acting on the CH-OH group of donor with other acceptors. The systematic name of this enzyme class is quinate:pyrroloquinoline-quinone 3-oxidoreductase. Other names in common use include NAD(P)+-independent quinate dehydrogenase, and quinate:pyrroloquinoline-quinone 5-oxidoreductase. This enzyme participates inphenylalanine, tyrosine and tryptophan biosynthesis .References
