Subject: Calculating vertical offset of helices From: Jie Liu jie {- at -} TRIMER {- dot -} MED {- dot -} CORNELL {- dot -} EDU Date: 2007-08-03
Dear CCP4ers:
Does anyone know an existing program to calculate the lateral displacement---the vertical offset, measured as a fraction of the the heptad repeat---of neighboring helices in coiled coils or helix bundles, either parallel or antiparallel?
Your input is greatly appreciated.
Have a nice weekend!
Jie
