EC 1.2.1.96     
Accepted name: 4-hydroxybenzaldehyde dehydrogenase (NADP+)
Reaction: 4-hydroxybenzaldehyde + NADP+ + H2O = 4-hydroxybenzoate + NADPH + 2 H+
Other name(s): p-hydroxybenzaldehyde dehydrogenase (ambiguous); pchA (gene name)
Systematic name: 4-hydroxybenzaldehyde:NADP+ oxidoreductase
Comments: Involved in the aerobic pathway for degradation of toluene, 4-methylphenol, and 2,4-xylenol by several Pseudomonas strains. The enzyme is also active with 4-hydroxy-3-methylbenzaldehyde. cf. EC 1.2.1.64, 4-hydroxybenzaldehyde dehydrogenase (NAD+).
