What's a GeneRIF?
  1. Results suggest that Leu may be a suitable replacement for Phe223 in the oxidative half-reaction of E. coli methylenetetrahydrofolate reductase.
    Title: Functional role for the conformationally mobile phenylalanine 223 in the reaction of methylenetetrahydrofolate reductase from Escherichia coli.
  2. The invariant aspartate 120 is a critical residue for E. coli methylenetetrahydrofolate reductase, with major roles in folate binding and catalysis, and a minor role in redox modulation.
    Title: Aspartate 120 of Escherichia coli methylenetetrahydrofolate reductase: evidence for major roles in folate binding and catalysis and a minor role in flavin reactivity.
  3. Multiple onformation, which allows aspartic acid 120 to hydrogen bond to the pterin ring in the folate complex but must move to an "open" conformation to allow NADH to bind.
    Title: Structures of NADH and CH3-H4folate complexes of Escherichia coli methylenetetrahydrofolate reductase reveal a spartan strategy for a ping-pong reaction.
