Figure 1From: Structural basis of regulation and substrate specificity of protein kinase CK2 deduced from the modeling of protein-protein interactionsModel of PKCK2α with substrate peptide (red) in 'turning' conformation. Catalytic base Asp (green) in the kinase and phospho acceptor Ser in the substrate (orange) are also shown. The other important substrate binding residues are indicated in dark blue in the ball and stick representation. Figure generated using SETOR [44].Back to article page
