1 Preliminary joint X-ray and neutron protein crystallographic studies of ecDHFR complexed with folate and NADP+. NADP dihydrofolate reductase Escherichia coli
2 A crystal of Escherichia coli dihydrofolate reductase (ecDHFR) complexed with folate and NADP+ of 4x1.3x0.7 mm (3.6 mm3) in size was obtained by sequential application of microseeding and macroseeding. NADP dihydrofolate reductase Escherichia coli
3 The neutron and X-ray data were used together for joint refinement of the ecDHFR-folate-NADP+ ternary-complex structure in order to examine the protonation state, protein dynamics and solvent structure of the complex, furthering understanding of the catalytic mechanism. NADP dihydrofolate reductase Escherichia coli
