PF02310B12 binding domain (B12-binding)B12 binding domainThis domain binds to B12 (adenosylcobamide)[1-3], it is found in several enzymes, such as glutamate mutase Swiss:Q05488, methionine synthase Swiss:Q99707 and methylmalonyl-CoA mutase Swiss:P22033. It contains a conserved DxHxxGx(41)SxVx(26)GG motif, ...This domain binds to B12 (adenosylcobamide)[1-3], it is found in several enzymes, such as glutamate mutase Swiss:Q05488, methionine synthase Swiss:Q99707 and methylmalonyl-CoA mutase Swiss:P22033. It contains a conserved DxHxxGx(41)SxVx(26)GG motif, which is important for B12 binding [2].
