Discovery and characterization of a novel p-hydroxybenzoate-m-hydroxylase, protocatechuate 3,4 ring-cleavage dioxygenase and hydroxyquinol 1,2 ring-cleavage dioxygenase from Aspergillus niger

The aim of this study was to find candidate genes in A. niger involved in the degradation of benzoic acid. Transcriptome data on aromatic compounds was used to find candidate genes encoding benzoic acid metabolic enzymes
