šIs 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
