Y71F/T169Y | mutant designed to mimic the betaine-homocysteine methyltransferase substrate binding pocket, complete loss of activity | Escherichia coli |

additional information | contrary to human enzyme, K+ is not required | Escherichia coli | |
Zn2+ | required. The metallated crystal form has residues C229, C295 and C296 coordinated to a Zn2+ center. the coordination of homocysteine to metal with a distance of 2.8 A contributes to near-ideal Zn2+-centered tetrahedron geometry | Escherichia coli |
