EC 126.96.36.199 Enzyme
4-hydroxybenzaldehyde dehydrogenase (NAD+);
p-hydroxybenzaldehyde dehydrogenase (ambiguous);
4-hydroxybenzaldehyde dehydrogenase (ambiguous)
Acting on the aldehyde or oxo group of donors;
With NAD+ or NADP+ as acceptor
4-hydroxybenzaldehyde + NAD+ + H2O = 4-hydroxybenzoate + NADH + 2 H+ [RN:
The bacterial enzyme (characterized from an unidentified denitrifying bacterium) is involved in an anaerobic toluene degradation pathway. The plant enzyme is involved in formation of 4-hydroxybenzoate, a cell wall-bound phenolic acid that plays a major role in plant defense against pathogens. cf. EC
, 4-hydroxybenzaldehyde dehydrogenase (NADP+).
