In enzymology, a (R)-4-hydroxyphenyllactate dehydrogenase (EC 220.127.116.11) is an enzyme that catalyzes the chemical reaction(R)-3-(4-hydroxyphenyl)lactate + NAD(P)+
The 3 substrates of this enzyme are (R)-3-(4-hydroxyphenyl)lactate, NAD+, and NADP+, whereas its 4 products are 3-(4-hydroxyphenyl)pyruvate, NADH, NADPH, and H+.
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (R)-3-(4-hydroxyphenyl)lactate:NAD(P)+ 2-oxidoreductase. Other names in common use include (R)-aromatic lactate dehydrogenase, and D-hydrogenase, D-aryllactate. This enzyme participates in tyrosine and phenylalanine catabolism.
