All crystal structures of A-DNA duplexes exhibit a typical crystal packing, with the termini of one molecule abutting the shallow grooves of symmetry related neighbors, while all other forms (B, Z, and RNA) tend to form infinitely stacked helices. The A-DNA arrangement leads to the formation of shal
## Abstract The crystal structure of the synthetic protected oligopeptide Zβ(Aib)~11~βO__t__Bu was determined by xβray crystallography. The undecapeptide folds in a regular 3~10~βhelix with nine consecutive 4 β 1 hydrogen bonds. At present, this is the largest available structure of a homopeptide (
