ID 1.97.1.2 DE pyrogallol hydroxytransferase. AN pyrogallol hydroxyltransferase. AN Transhydroxylase. CA 1,2,3,5-tetrahydroxybenzene + 1,2,3-trihydroxybenzene = 1,2,3,5- CA tetrahydroxybenzene + 1,3,5-trihydroxybenzene. CC -!- 1,2,3,5-Tetrahydroxybenzene acts as a cosubstrate for the conversion CC of pyrogallol into phloroglucinol, and for a number of similar CC isomerizations. CC -!- The enzyme is provisionally listed here, but might be considered as CC the basis for a new class in the transferases, analogous to the CC aminotransferases.
