Role of Electrostatic Interactions in Binding of Peptides and Intrinsically Disordered Proteins to Their Folded Targets: 2. The Model of Encounter Complex Involving the Double Mutant of the c-Crk N-SH3 Domain and Peptide Sos.

Abstract excerpt

In the first part of this work (paper 1, Xue, Y. et al. Biochemistry 2014 , 53 , 6473 ), we have studied the complex between the 10-residue peptide Sos and N-terminal SH3 domain from adaptor protein c-Crk. In the second part (this paper), we designed the double mutant of the c-Crk N-SH3 domain, W169F/Y186L, with the intention to eliminate the interactions responsible for tight peptide-protein binding, while...
