Synthesis and binding of stable bisubstrate ligands for phosphoglycerate kinase.
Stable bisubstrate ligands of phosphoglycerate kinase (PGK) have been synthesized with AMP or ADP conjugated to hydrolytically-stable, symmetrical analogues of 1,3-bisphosphoglycerate and their binding to yeast PGK evaluated. Their Kds decrease with net negative charge, with a penta-anionic analogue 7 showing highest affinity-in accordance with its approximation to the transition state for the reaction catalysed by PGK.
