PF16554Dimerisation domain of d-ornithine 4,5-aminomutase (OAM_dimer)Dimerisation domain of d-ornithine 4,5-aminomutaseThis family is the short dimerisation domain of the enzyme D-ornithine 4,5-aminomutase. It sits between the TIM-barrel Pfam:PF09043 and Pfam:PF02310.

It sits between the TIM-barrel Pfam:PF09043 and Pfam:PF02310. The enzyme is an alpha2-beta2-heterodimer that converts D-ornithine to 2,4-diaminopentanoic acid by way of radical propagation from an adenosylcobalamin to a pyridoxal 5'-phosphate cofactor [1].

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].

PF09043D-Lysine 5,6-aminomutase TIM-barrel domain of alpha subunit (Lys-AminoMut_A)D-Lysine 5,6-aminomutase TIM-barrel domain of alpha subunitMembers of his family are involved in the 1,2 rearrangement of the terminal amino group of DL-lysine and of L-beta-lysine, using adenosylcobalamin (AdoCbl) and pyridoxal-5'-phosphate as co-factors.

The structure is predominantly a PLP-binding TIM barrel domain, with several additional alpha-helices and beta-strands at the N and C termini. These helices and strands form an intertwined accessory clamp structure that wraps around the sides of the TIM barrel and extends up toward the Ado ligand of the Cbl co-factor, providing most of the interactions observed between the protein and the Ado ligand of the Cbl, suggesting that its role is mainly in stabilising AdoCbl in the precatalytic resting state [1]. This is a TIM-barrel domain.
