Sequential backbone resonance assignments of the E. coli dihydrofolate reductase Gly67Val mutant: folate complex.

Abstract excerpt

Occasionally, a mutation in an exposed loop region causes a significant change in protein function and/or stability. A single mutation Gly67Val of E. coli dihydrofolate reductase (DHFR) in the exposed CD loop is such an example. We have carried out the chemical shift assignments for H(N), N(H), C(α) and C(β) atoms of the Gly67Val mutant of E. coli DHFR complexed with folate at pH 7.0, 35 °C, and then evaluated...
