Synthesis and binding of stable bisubstrate ligands for phosphoglycerate kinase
摘要:
Stable bisubstrate ligands of phosphoglycerate kinase (PGK) have been synthesised with AMP or ADP conjugated to hydrolytically-stable, symmetrical analogues of 1,3-bisphosphoglycerate and their binding to yeast PGK evaluated. Their K(d)s 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.
