Fig 1. Crystal structure of ttCMPK.
(A) Overall structure of ttCMPK in complex with ADP, CDP, and Gd3+. The structure is shown in a schematic representation, colored in a spectrum from the N-terminus (blue) to the C-terminus (red). The bound nucleotides are shown in sticks. (B) Superimposition of the overall structure of ligand-free form (gray; PDB code 3W90), CMP "open" complex (cyan; 3W8N), CMP "closed" complex (green; 3AKE), ADP-CDP-Gd3+ complex (orange; 3AKC), and CDP complex (olive; 3AKD).
