Contains pyridoxal 5′-phosphate. The enzyme, characterized from the bacterium Mycobacterium smegmatis, cayalyses the last step in the pathway of ergothioneine biosynthesis. The enzyme forms a 2-sulfenohercynine intermediate, which is reduced to ergothioneine non-enzymically by a thiol. In vitro, DTT can serve this function.
