WebApr 8, 2024 · Circular dichroism studies pointed out that at higher concentrations, CB [7] interacted with both Phe B1 and Phe B24 residues and prevented the formation of insulin dimers. Molecular dynamics (MD) simulations also suggested that CB [7] hindered insulin dimers formation by binding to Phe B24 residue. WebThe superior stability of the computationally refined models was experimentally verified by circular dichroism and nuclear magnetic resonance spectroscopy. A crystal structure of a dArmRP containing the novel N-cap revealed that the enhanced stability correlates with an improved packing of this N-cap onto the hydrophobic core of the dArmRP.
