Domain

Cobalamin-independent methionine synthase MetE, N-terminal (IPR013215)

Short name: Cbl-indep_Met_Synth_N

Domain relationships

None.

Description

Cobalamin-independent methionine synthase, MetE, catalyses the synthesis of the amino acid methionine by the transfer of a methyl group from methyltetrahydrofolate to homocysteine [PMID: 15326182]. The N-terminal and C-terminal domains of MetE together define a catalytic cleft in the enzyme. The N-terminal domain is thought to bind the substrate, in particular, the negatively charged polyglutamate chain. The N-terminal domain is also thought to stabilise a loop from the C-terminal domain.
