HpaB Swiss:Q57160 encodes part of the 4-hydroxyphenylacetate 3-hydroxylase from Escherichia coli [2]. HpaB is part of a heterodimeric enzyme that also requires HpaC. The enzyme is NADH-dependent and uses FAD as the redox chromophore. This family also includes PvcC Swiss:O30372 may play a role in one of the proposed hydroxylation steps of pyoverdine chromophore biosynthesis [1]. [1]. 10383985.
