Protein Classification

MAPEG family protein( domain architecture ID 10471516)

MAPEG (Membrane Associated Proteins in Eicosanoid and Glutathione metabolism) family protein is a membrane associated protein; similar to mammalian prostaglandin E synthase, leukotriene C4 synthase, arachidonate 5-lipoxygenase-activating protein, microsomal glutathione S-transferases, and mitochondrial glutathione S-transferase 3

MAPEG family; This family is has been called MAPEG (Membrane Associated Proteins in Eicosanoid and Glutathione metabolism). It includes proteins such as Prostaglandin E synthase. This enzyme catalyzes the synthesis of PGE2 from PGH2 (produced by cyclooxygenase from arachidonic acid). Because of structural similarities in the active sites of FLAP, LTC4 synthase and PGE synthase, substrates for each enzyme can compete with one another and modulate synthetic activity.
