Re: [ccp4bb] coiled coil question

[Sergei Strelkov]

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 Dear Xie, there is a plenty of coiled coils that sit on crystallographic 2, 3... -folds. Examples: 1x8y (dimer), 1ox3 (trimer), ... Why do you ask? ;) Sergei
