The Cobalamin binding domain has a special characteristic in that, it is most naturally found in a protective conformation to prevent unwanted chemistry from occurring (PDB: 1BMT). This is referred to as a 'capping' mechanism. | The Cobalamin binding domain has a special characteristic in that, it is most naturally found in a protective conformation to prevent unwanted chemistry from occurring (PDB: 1BMT).
