Isocitrate lyase (EC=4.1.3.1), localized in glyoxysome is an enzyme involved in mobilization of storage lipis during plant seedling growth. Catalalyzed reaction is a conversion of isocitrate to succinate and glyoxylate. Alternative names of this enzyme: isocitrase, isocitritase, isocitratase, glyoxylate-lyase, isocitrate glyoxylatelyase.
