Subject: coiled coil question From: Xie Jiabao xie {- dot -} jiabao {- at -} YAHOO {- dot -} COM Date: 2009-10-03
Dear all,
Is anyone aware of a structure where the individual alpha helical chains of a coiled coil are related by a crystallographic axis? Or does anyone know of a coiled coil structure (dimer or higher order oligomer) that is perfectly symmetric at least in terms of the protein backbone or alpha carbon atoms?
Thanks and best regards, Xie
