Figure 7From: Functional asymmetry in the lysyl-tRNA synthetase explored by molecular dynamics, free energy calculations and experimentTime evolution of the molecular mechanical interaction energies between ATP and Arg 269. A decrease in the interaction energy between ATP and Arg 269 at site 1 (black trace) is correlated to an increased interaction energy between ATP and Arg 269 at site 2 (grey trace).Back to article page
