Domain

Methionine synthase, B12-binding domain (IPR033706)

Short name: Met_synthase_B12-bd

Overlapping homologous superfamilies

Domain relationships

None.

Description

This domain is the B12 binding domain of methionine synthase. Methionine synthase binds methylcobalamin (B12), which it uses as an intermediate methyl carrier from methyltetrahydrofolate (CH3H4folate) to homocysteine to yield tetrahydrofolate and L-methionine [PMID: 7712296, PMID: 11731805, PMID: 10730193].
