Default protein-protein complex structure determination

protein-protein complex structure determination

Dear Friends,

I am working on a protein-protein complex using 700MHz VARIAN NMR . I have done HSQC perturbation studies by adding incremental ratio of protein A to B, and doing the reverse way adding protein B to A. In both the spectrum I have noticed about 20 peaks disappear or peak intensity drop in both spectrum . The total complex size I assume to be in range of 50kD. Would it be reasonable to proceed further and acquire 3D experiments for protein-protein complex structure calculation ? Any suggestions would be useful.

thanks & regards

Arun
