2.1.2.10 [protein]-S8-aminomethyldihydrolipoyllysine + tetrahydrofolate = [protein]-dihydrolipoyllysine + 5,10-methylenetetrahydrofolate + NH3 - - 2.1.2.10 [protein]-S8-aminomethyldihydrolipoyllysine + tetrahydrofolate = [protein]-dihydrolipoyllysine + 5,10-methylenetetrahydrofolate + NH3 5-methyltetrahydrofolate is bound in a kinked shape with the pteridine group deeply buried into the hydrophobic pocket ant the glutamyl group pointed to the C-terminal side surface. R292 interacts through water molecules with the folate polyglutamate tail 662653 2.1.2.10 [protein]-S8-aminomethyldihydrolipoyllysine + tetrahydrofolate = [protein]-dihydrolipoyllysine + 5,10-methylenetetrahydrofolate + NH3 formation of a folate-binding cavity via the interaction of enzyme with H-protein 662123 2.1.2.10 [protein]-S8-aminomethyldihydrolipoyllysine + tetrahydrofolate = [protein]-dihydrolipoyllysine + 5,10-methylenetetrahydrofolate + NH3 T-protein recognition of lipoyl protein substrate and reaction mechanism, overview. The reversible transfer of the methylene group between the lipoate and tetrahydrofolate proceeds through the electron relay-assisted iminium intermediate formation 719865 2.1.2.10 [protein]-S8-aminomethyldihydrolipoyllysine + tetrahydrofolate = [protein]-dihydrolipoyllysine + 5,10-methylenetetrahydrofolate + NH3 tetrahydrofolate is bound near the center of the tripartite enzyme, lipoic acid is bound adjacent to the tetrahydrofolate binding pocket 662303
