The details of dimeric interfaces of the SYCP1 CC structure.

<p>(A) Interhelical interactions of coiled coil within the asymmetric unit of the seleno-methionine crystal are shown. The residues in the positions a and d of heptad repeats are presented as a stick model at the top panel. Close-up views of three different parts are shown. The amino acid residues that participated in the interhelical interactions are labelled. L; Left, M; Middle, R; Right. (B) Helical wheel presentation of the heptad repeats in SYCP1 CC. Interhelical charged interactions are indicated by a red-line connecting paired residues. Charged residues and hydrophobic residues are colored blue and red, respectively.
