Protein: Benzoate 4-monooxygenase bphA (EC 1.14.14.92) (Benzoate-para-hydroxylase A) (BpH) (Cytochrome P450 monooxygenase cyp53A1) (P17549)
Organism: Aspergillus niger
Function: Cytochrome P450 monooxygenase; part of the benzoic acid degradation pathway also known as the protocatechuic acid pathway. Benzoic acid debradation begins with the conversion of benzoic acid into 4-hydroxybenzoic acid through hydroxylation by the benzoate-4-monooxygenase bphA, and its partner NADPH-cytochrome P450 reductase cprA which act as a mediator in electron donation from NADPH. 4-Hydroxybenzoic acid is then converted into 3,4-dihydroxybenzoic acid (also called protocatechuic acid) by the p-hydroxybenzoate-m-hydroxylase phhA (Ref.6). Protocatechuic acid is converted into 3-carboxy-cis,cis-muconic acid by the intradiol ring-cleavage dioxygenase prcA, which is further metabolized through the 3-oxoadipate pathway to finally enter the tricarboxylic acid cycle (TCA) (Ref.6).
