Primary referenceCoiled coils at the edge of configurational heterogeneity. Structural analyses of parallel and antiparallel homotetrameric coiled coils reveal configurational sensitivity to a single solvent-exposed amino acid substitution., Yadav MK, Leman LJ, Price DJ, Brooks CL 3rd, Stout CD, Ghadiri MR, Biochemistry. 2006 Apr 11;45(14):4463-73.
