Fig. 4From: Structural prediction of the interaction of the tumor suppressor p27KIP1 with cyclin A/CDK2 identifies a novel catalytically relevant determinantSuperposition of cyclin A/CDK2/p27KIP1 peptide (amino acids 180–194) with the PKA/ATP/2 Mn2+ crystal structure (PDB ID: 1AST [36]). The second Mn2+ in PKA is indicated by cyan sphere. The cartoon representations of CDK2 and p27KIP1 are colored in blue and green, respectively. PKA is colored in cyan. PKA residues are labeled with primeBack to article page
