ADP + 1,3-bisphosphoglycerate using the stopped-flow method it is shown that substrate binding kinetics that lead to the formation of the catalytic PGK-1,3-bisphosphoglycerate-ADP complexes are mutually antagonistic with D-ADP, but much less so with L-ADP. A situation that is similar to that for the formation of the abortive PGK-3-phosphoglycerate-ADP complexes Homo sapiens ATP + 3-phosphoglycerate

L-ADP + 1,3-bisphosphoglycerate with L-ADP, the transient burst phase of ATP is more clear-cut than with D-ADP, suggesting that the product release steps are slower with L-ADP than with D-ADP. This is in accordance with the lower kcat measured with L-ADP compared to D-ADP Homo sapiens ?
