1 To address the effects of ligand binding on the structural fluctuations of Escherichia coli dihydrofolate reductase (DHFR), the hydrogen/deuterium (H/D) exchange kinetics of its binary and ternary complexes formed with various ligands (folate, dihydrofolate, tetrahydrofolate, NADPH, NADP(+), and methotrexate) were examined using electrospray ionization mass spectrometry. dihydrofolate Dihydrofolate reductase Escherichia coli
