Capture and quality control mechanisms for adenosine-5'-triphosphate binding.

Journal of the American Chemical Society - 24 Apr 2013

Li Li, Martinis Susan A, Luthey-Schulten Zaida

Abstract excerpt

The catalytic events in members of the nucleotidylyl transferase superfamily are initiated by a millisecond binding of ATP in the active site. Through metadynamics simulations on a class I aminoacyl-tRNA synthetase (aaRSs), the largest group in the superfamily, we calculate the free energy landscape of ATP selection and binding. Mutagenesis studies and fluorescence spectroscopy validated the identification of the...
