2-hydroxy-4-carboxymuconate semialdehyde hemiacetal dehydrogenase

The enzyme does not act on unsubstituted aliphatic or aromatic aldehydes or glucose; NAD+ can replace NADP+, but with lower affinity. The enzyme was initially believed to act on 4-carboxy-2-hydroxy-cis,cis-muconate 6-semialdehyde and produce 4-carboxy-2-hydroxy-cis,cis-muconate. However, later studies showed that the substrate is the hemiacetal form, and the product is 2-oxo-2H-pyran-4,6-dicarboxylate.
