Connecting Protein Conformational Dynamics with Catalytic Function as Illustrated in Dihydrofolate Reductase

Combined QM/MM molecular dynamics simulations reveal that the M20 loop conformational dynamics of dihydrofolate reductase (DHFR) is severely restricted at the transition state of the hydride transfer as a result of the M42W/G121V double mutation. Consequently, the double mutant enzyme has a reduced...
