P25665 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferase; Cobalamin-independent methionine synthase; Methionine synthase, vitamin-B12 independent isozyme; EC 2.1.1.14 from Escherichia coli (strain K12) (see 3 papers)
57% identity, 95% coverage: 30:801/810 of query aligns to 3:751/753 of P25665
- H641 (= H691) mutation to N: Impaired activity, lower affinity for zinc binding.; mutation to Q: Impaired activity, lower affinity for zinc binding. Binds homocysteine 2-4x more weakly than wild-type.
- C643 (= C693) mutation to S: Impaired activity, lower affinity for zinc binding. Binds homocysteine 7x tighter than wild-type.
- C726 (= C776) mutation to S: Impaired activity, lower affinity for zinc binding. Binds homocysteine 2-4x more weakly than wild-type.
