Also included in the alignment, but not GSTs: S-crystallins from squid (similarity to GST previously noted); eukaryotic elongation factors 1-gamma (not known to have GST activity and similarity not previously recognised); HSP26 family of stress-related proteins including auxin-regulated proteins in plants and stringent starvation proteins in E. coli (not known to have GST activity and similarity not previously recognised). The glutathione molecule binds in a cleft between the N- and C-terminal domains - the catalytically important residues are proposed to reside in the N-terminal domain [1].

prostaglandin-D synthase  M-CSA #719

Hematopoietic prostaglandin-D synthase (H-PGDS) is a homodimer in an asymmetric unit. Each monomer is complexed with one glutathione (GTT or GSH) molecule. H-PGDS is one of two types of prostaglandin-D synthase (PGDS) that catalyses the isomerisation of PGH2 to PGD2. PGD2 is a lipid mediator produced by a variety of cells of the immune system, including Th2 and mast cells, that accelerates allergic and inflammatory responses, regulates body temperature, inhibits platelet aggregation, promotes sleep and numerous other physiological functions. H-PGDS is also a member of the glutathione S-transferase (GST) gene family, a group of enzymes that catalyse the conjugation of GSH to an electrophilic substrate.
