1.1.1.40 | tetramer | a dimer of dimers. The c-NADP-ME monomer is composed of four domains. Domain A (residues 23-130) is predominantly helical and confers the ability to bind fumarate. Domain B (residues 131-277 and 464-535) contains a central five-stranded parallel beta-sheet surrounded by helices on both sides. Domain C (residues 278-463) exhibits a dinucleotide-binding Rossmann fold with a modification: strand beta3 is replaced by a short antiparallel beta-strand. Domain D (residues 536-579) contains one helix followed by a long extended random coil structure protruding away from the ordered portion of the ME monomer. The active site of ME is located at the interface of domains B and C, whereas residues in domains A and D primarily participate in the formation of dimers and tetramers | Homo sapiens |

1.1.1.38 | additional information | the molecular basis for the different allosteric properties and quaternary structural stability of m-NAD(P)-ME, EC 1.1.1.38 and c-NADP-ME, EC 1.1.1.40. The structural features near the fumarate binding site and the dimer interface are highly related to the quaternary structural stability of c-NADP-ME and m-NAD(P)-ME. Lys57 plays functional roles in both the allosteric regulation and the subunit-subunit interaction of humanm-NAD(P)-ME | Homo sapiens |
1.1.1.40 | additional information | the molecular basis for the different allosteric properties and quaternary structural stability of m-NAD(P)-ME, EC 1.1.1.39 and c-NADP-ME, EC 1.1.1.40. The structural features near the fumarate binding site and the dimer interface are highly related to the quaternary structural stability of c-NADP-ME and m-NAD(P)-ME | Homo sapiens |
