Hi I would like to know whether it is possible to get to know the number of molecules (helices) present in a coiled coil based on its XRD pattern.
I only know that for coiled coil there will be a meridian arc around 5.1 A (corresponding to helical repeat) and an equatorial arc around 10 A (corresponding to mean distance between helical axes). I am actually curious to know whether it is possible to distinguish double from triple stranded coiled coil from its XRD pattern. Thank you Uday
