The ...The N-terminal domain and C-terminal domains of cobalamin-independent synthases 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 [1].

PF01717Cobalamin-independent synthase, Catalytic domain (Meth_synt_2)Cobalamin-independent synthase, Catalytic domainThis is a family of vitamin-B12 independent methionine synthases or 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferases, EC:2.1.1.14 from bacteria and plants. Plants are the only higher eukaryotes that have the required enzymes for ...This is a family of vitamin-B12 independent methionine synthases or 5-methyltetrahydropteroyltriglutamate--homocysteine methyltransferases, EC:2.1.1.14 from bacteria and plants. Plants are the only higher eukaryotes that have the required enzymes for methionine synthesis [1]. This enzyme catalyses the last step in the production of methionine by transferring a methyl group from 5-methyltetrahydrofolate to homocysteine [1]. The aligned region makes up the carboxy region of the approximately 750 amino acid protein except in some hypothetical archaeal proteins present in the family, where this region corresponds to the entire length. This domain contains the catalytic residues of the enzyme [2].
