   4.2.1.28 | Ca2+ |
1.6-1.9 mol/mol of enzyme. CaCl2 and substrate show not only a stabilizing effect but also some activating effect of about 30% |

| 4.2.1.28 | Ca2+ |
directly coordinates to substrate and is essential for structural retention and substrate binding |

| 4.2.1.28 | Co2+ |
in the cob(II)alamin cofactor |
696252 |
| 4.2.1.28 | Co2+ |
in the cobalamin cofactor |
698752 |
| 4.2.1.28 | Co2+ |
in the cobalamin cofactor, presence of a positive charge at the beta135 residue increases the affinity for cobalamins but is not essential for catalysis, and the introduction of a negative charge there prevents the enzyme-cobalamin interaction |
697886 |
| 4.2.1.28 | Co2+ |
the is dependent on coenzyme B12, adenosylcobalamin |
698651 |
