Protein Family Annotation Pfam Database Homepage

Chains Pfam Accession Pfam Identifier Pfam Description Type Source
A PF02607 B12-binding_2 B12 binding domain Domain This B12 binding domain is found in methionine synthase EC:2.1.1.13 Swiss:Q99707, and other shorter proteins that bind to B12. This domain is always found to the N-terminus of Pfam:PF02310. The structure of this domain is known [1], it is a 4 helix bundle. Many of the conserved residues in this domain are involved in B12 binding, such as those in the MXXVG motif. PFAM PF02607
A PF02310 B12-binding B12 binding domain Domain 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]. PFAM PF02310
A PF02965 Met_synt_B12 Vitamin B12 dependent methionine synthase, activation domain Domain PFAM PF02965
