1.8.5.7	additional information	PcpF catalyzes glutathione-dependent reduction of glutathionyl-trichloro-p-hydroquinone via a Ping Pong mechanism. First, PcpF reacts with glutathionyl-trichloro-p-hydroquinone to release trichloro-p-hydroquinone and forms a disulfide bond between its Cys53 residue and the glutathione moiety. Then, a glutathione comes in to regenerate PcpF and release glutathione disulfide
