Probing ATP/ATP-Aptamer or ATP-Aptamer Mutant Complexes by Microscale Thermophoresis and Molecular Dynamics Simulations: Discovery of an ATP-Aptamer Sequence of Superior Binding Properties.

Abstract excerpt

Microscale thermophoresis (MST) is used to follow the dissociation constants corresponding to ATTO 488-labeled adenosine triphosphate (ATP) and the ATP-aptamer or ATP-aptamer mutants that include two binding sites for the ATP ligand. A set of eight ATP-aptamer mutants, where the thymidine bases, within the reported ATP binding aptamer sites, are substituted with cytosine bases, are examined. The MST-derived...
