For some starting points, google "electrostatic interactions in intrinsically disordered proteins". Of course they occur in IDPs; they even have proportionally more charged residues than folded proteins. Petri On Nov 3, 2012, at 5:06 PM, Xiaodi Yu wrote: > Dear All: > > I have a quick questi

Dee, Intramolecular electrostatic interactions are common in protein structures, for example between i and i+4 pairs on the same face of a helix. Robert Baldwin (Stanford) and others did a lot of work on the contribution of intramolecular salt bridges to helix stabilization in model helices. If

Dear All: I have a quick question: how common it is that electrostatic interactions are involved in intra-molecular interactions, particularly in intrinsically disordered proteins? Is this interaction specific and any example? Thanks, Dee Xiaodi Yu, Ph.D. Boston Children's Hospital & Dana-Fa
