Early mutagenesis studies of the Arabidopsis GS identified a putative glycine-rich loop as important for activity (Wang and Oliver, 1997a,b), which was identified in later structural studies as forming part of the active site (Galant et al., Arabidopsis GS uses a random Ter-reactant mechanism with binding of either ATP or -glutamylcysteine preferred first and addition of glycine last (Jez and Cahoon, Arabidopsis GS and for the eukaryotic homologs (Herrera et al., 2+ to ATP and orienting the -phosphate group in the active site
