Aromatic 2-oxoacid reductase
In enzymology, an aromatic 2-oxoacid reductase is an enzyme that catalyzes the reversible oxidation and reduction of aryllactate compounds to arylpyruvate compounds using the redox cofactor nicotinamide adenine dinucleotide or the similar nicotinamide adenine dinucleotide phosphate. For example, the enzyme may oxidize -3-lactate to 3-pyruvic acid.
This enzyme is an oxidoreductase, oxidizing the CH-OH alcohol group to a carbonyl group. NAD+ is the oxidizing agent, yielding reduced NADH.
Aryllactates and arylpyruvates are intermediates in tyrosine, phenylalanine and tryptophan metabolism and blood serum levels of these compounds affect intestinal permeability and systemic immunity in mice.
Alternative names for these enzymes are: -aromatic lactate dehydrogenase, D-aryllactate D-hydrogenase, lactate:NAD+ oxidoreductase, indolelactate:NAD+ oxidoreductase, -4-hydroxyphenyllactate dehydrogenase, '''-3-lactate:NAD 2-oxidoreductase'''
