4-aminobenzoate 1-monooxygenase (EC 1.14.13.27) is an enzyme that catalyzes the chemical reaction

+ NADH + H+
 
 
O2
H2O
 
 
 
+ NAD+ + CO2
 

The four substrates of this enzyme are 4-aminobenzoic acid, reduced nicotinamide adenine dinucleotide (NADH), oxygen and a proton. Its products are 4-aminophenol, oxidised NAD+, water, and carbon dioxide. Nicotinamide adenine dinucleotide phosphate can be used as an alternative cofactor.[1][2]

The enzyme is a flavin-containing monooxygenase that uses molecular oxygen as oxidant and incorporates one of its atoms into the starting material. The systematic name of this enzyme class is 4-aminobenzoate,NAD(P)H:oxygen oxidoreductase (1-hydroxylating, decarboxylating). Other names in common use include 4-aminobenzoate hydroxylase, and 4-aminobenzoate monooxygenase. It uses flavin adenine dinucleotide as a cofactor.[1]
