Figure 2: Interactions of the cobalamin cofactor and RACo.
From: ATP-induced electron transfer by redox-selective partner recognition

(a) Residues of RACo (pink) interacting with the corrin ring (cyan stick model) are shown as sticks and interactions are denoted by black dashes. (b) Cobalamin (spheres) confined in the corrin-binding pocket of RACo (pink surface).
