Phi psi bonds
Webb1 maj 2016 · The prediction of change in stability upon point mutations in proteins has many applications in protein analysis and engineering. We recently adjoined a new structure-based method called MAESTRO, which is distributed as command line program. We now provide access to the most important features of MAESTRO by an easy to use … http://folding.chemistry.msstate.edu/~raj/Research/Linus/phipsi.html
