The association of two proteins is preceded by a mutual diffusional search in solution. The role of translational and rotational diffusion in this process has been studied theoretically for many years. However, systematic experimental verification of theoretical results is still lacking. We report here measurements of association rates of the proteins(More)
The third variable region (V3) of the HIV-1 envelope glycoprotein gp120 is a target for virus neutralizing antibodies. The V3 sequence determines whether the virus will manifest R5 or X4 phenotypes and use the CCR5 or CXCR4 chemokine coreceptor, respectively. Previous NMR studies revealed that both R5- and X4-V3 peptides bound to antibodies 0.5beta and(More)
