General annotation (Comments)

Catalytic activity

Trans-1,2-dihydrobenzene-1,2-diol + NADP+ = catechol + NADPH.

D-xylose + NADP+ = D-xylono-1,5-lactone + NADPH.

Enzyme regulation

Strongly inhibited by isoascorbic acid, 4-hydroxyacetophenone and chloromercuriphenylsulphonate. Stimulated by various salts. Ref.1 Ref.2 Ref.3

Subunit structure

Homodimer. Ref.1 Ref.2

Tissue specificity

Kidney. Ref.1

Sequence similarities

Belongs to the gfo/idh/mocA family.

Experimental info

Mutagenesis791H → E: Decrease in K(d) and K(m) value for NADPH. Elimination of the fluorescence-energy transfer and enhancement of NADPH fluorescence by the binary complex formation. Potent inhibition of the dehydrogenase activity by high ionic strength. Ref.2
Mutagenesis1801Y → F: Significant loss of activity. No effect on the high affinity for NADPH, fluorescence-energy transfer and enhancement of NADPH fluorescence by the binary complex formation. Ref.2
