本酶催化的反应为S-(Hercyn-2-Yl)-L-Cysteine S-Oxide + Reduced Acceptor = Ergothioneine + Pyruvate + NH3 + Acceptor (Overall Reaction);;(1a) S-(Hercyn-2-Yl)-L-Cysteine S-Oxide + H2O = 2-(Hydroxysulfanyl)hercynine + Pyruvate + NH3;;(1b) 2-(Hydroxysulfanyl)hercynine + Reduced Acceptor = Ergothioneine + Acceptor + H2O (Spontaneous)，系统名称为S-(Hercyn-2-Yl)-L-Cysteine Ergothioneine-Hydroxysulfanolate-Lyase，含有磷酸吡哆醛。该酶源自龟脓分枝杆菌（Mycobacterium smegmatis），催化麦角硫因生物合成途径的最后一步。该酶形成 2-(羟基硫基)组氨酸甜菜碱中间体，后者被硫醇非酶促还原为麦角硫因。体外实验中 DTT 可承担此功能。
