In the loop 2-2, a charged residue (lysine, arginine), not present in all GSTs, makes a salt bridge with the carboxyl group of GlyGS (glycine residue of glutathione)
A recent study showed that PPT1 regulates systemic autoimmunity by removing S-palmitoylation from C258 and C265 of TLR9 in lysosomes, promoting the secretion of TNF by macrophages in systemic lupus erythematosus ( 151 )
