Figure 8From: Cα-H···O=C hydrogen bonds contribute to the specificity of RGD cell-adhesion interactionsAn array of four hydrogen bonds, two N-H···O=C (in yellow) and two C-H···O=C (in green), line up the bottom of the c RGD peptide against the integrin surface. The two weak Cα/β-H···O=C interactions thus contribute to the specificity of binding and presumably also have a cooperative effect on stability.
