ternary complex mechanism in which the aromatic substrate has strict control in both the reductive and oxidative half-reaction in a way that reactions leading to substrate hydroxylation are favored over those leading to the futile formation of hydrogen peroxide. NAD+ release from the reduced enzyme-substrate complex is the slowest step in catalysis

wild-type enzyme HbpA has a broad substrate range and catalyzes the regioselective ortho-hydroxylation of a wide range of 2-substituted phenols to the corresponding catechols. It possess pro-S enantioselectivity towards the production of several chiral sulfoxides, whereas its mutant variant M321F exhibits improved enantioselectivity, while mutant M321A shows altered regioselectivity by oxidizing 3-hydroxybiphenyl, and thus enabling the production of a distinct antioxidant, 3,4-dihydroxybiphenyl.
