Stringent starvation proteins in E. coli are also included in the alignment but are not known to have GST activity. The glutathione molecule binds in a cleft between N and C-terminal domains. The catalytically important residues are proposed to reside in the N-terminal domain [1]. In plants, GSTs are encoded by a large gene family (48 GST genes in Arabidopsis) and can be divided into the phi, tau, theta, zeta, and lambda classes [2].

Glutathione S-transferase class-μ  M-CSA #867

Glutathione S-transferases (GSTs) are promiscuous enzymes that catalyze several reactions with various substrates. Their essential function is detoxification of xenobiotic compounds that are conjugated to glutathione (GSH) and then excreted; other functions, not associated with detoxification, include repair of macromolecules oxidised by reactive oxygen species, regeneration of S-thiolated proteins, and biosynthesis of physiologically important metabolites. There are two proposed mechanisms regarding GSH activation depending on the conformation of Tyr10 (in and out). Both appear to be viable where evidence supports both conformations.
