The ...Details: The authors state that for the structure of the calmodulin C-lobe, they used residues 82-149 from the available structure of the calmodulin/IQ domain complex (PDB ID - 2F3Y, chain A). The structure of the peptide fragment of the Cyclic nucleotide-gated cation channel beta-1 was generated in Modeller 9.25 using the template of creatine kinase peptide (PDB ID - 7BF2, chain B[auth DDD]). Finally, the HADDOCK calculation was performed on an energy minimized peptide obtained after energy minimization in Gromacs. | |||||||||||||||
