Reaction: leukotriene C4 + H2O = leukotriene D4 + L-glutamate
Other name(s): γ-glutamyl leukotrienase; GGT5
Comments: The mouse enzyme is specific for leukotriene C4, while the human enzyme also has considerable activity towards glutathione and oxidized glutathione (cf. EC 3.4.19.13, glutathione hydrolase) [3-4].
