Members 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.	Domain

This 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. 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].

OAM_alpha is the 12.8kDa, alpha subunit of d-ornithine 4,5-aminomutase, or OAM, an enzyme that converts d-ornithine to 2,4-diaminopentanoic acid by way of radical propagation from an adenosylcobalamin to a pyridoxal 5'-phosphate cofactor. OAM is an alpha2-beta2 heterodimer comprising two strongly associating subunits. The packing of the alpha subunits against the beta helps to form the substrate and co-factor binding-regions [1].
