Sysname
D-apionate:NAD+ oxidoreductase (isomerizing)
Reaction(IUBMB)
D-apionate + NAD+ = 3-oxoisoapionate + NADH + H+ [RN:
R12503 ]
Reaction(KEGG)
Substrate
Product
Comment
The enzyme, characterized from several bacterial species, participates in the degradation of D-apionate. The reaction involves migration of a hydroxymethyl group from position 3 to position 2 and oxidation of the 3-hydroxyl group. Stereospecificity of the product, 3-oxoisoapionate, has not been determined.
