Pump for glutathione S-conjugates. Mediates the transport of glutathione conjugates such as chlorodinitrobenzene-GS (DNB-GS), and of chlorophyll catabolites such as Bn-NCC-1. Transports also heavy metals such as cadmium (Cd). ATP + H2O + xenobioticSide 1 = ADP + phosphate + xenobioticSide 2. Glutathione-conjugate transport is inhibited by decyl-glutathione and, to a lower extent, by GS-GS, but not by GSH. All transports are inhibited by vanadate. Ubiquitous. By 1-chloro-2,4-dinitrobenzene (CDNB), primisulfuron (PS), aminotriazole, benoxacor, oxabetrinil and IRL 1803, and, to a lower extent, by cloquintocet, fenchlorazol and fluorazol. Belongs to the ABC transporter superfamily. ABCC family. Conjugate transporter (TC 3.A.1.208) subfamily.
