GSH_synth_ATP

GSH_synth_ATP
PFAM accession number:PF03917
Interpro abstract (IPR005615):

This entry represents glutathione synthetase ( EC 6.3.2.3 ) (GSS), a homodimeric enzyme that catalyses the conversion of gamma-L-glutamyl-L-cysteine and glycine to phosphate and glutathione in the presence of ATP. This is the second step in glutathione biosynthesis, the first step being catalysed by gamma-glutamylcysteine synthetase [ (PUBMED:15981742) ]. In humans, defects in GSS are inherited in an autosomal recessive way and are the cause of severe metabolic acidosis, 5-oxoprolinuria, and increased rate of haemolysis and defective function of the central nervous system.

GO process:glutathione biosynthetic process (GO:0006750)
GO function:glutathione synthase activity (GO:0004363), ATP binding (GO:0005524)
