Sysname
L-dopachrome keto-enol isomerase
Reaction(IUBMB)
L-dopachrome = 5,6-dihydroxyindole-2-carboxylate [RN:R03673]
Reaction(KEGG)
Substrate
L-dopachrome [CPD:C01693]
Product
5,6-dihydroxyindole-2-carboxylate [CPD:C04185]
Comment
A zinc enzyme. Stereospecific for L-dopachrome. Dopachrome methyl ester is a substrate, but dopaminochrome (2,3-dihydroindole-5,6-quinone) is not (see also EC 4.1.1.84, D-dopachrome decarboxylase).
