From (φ,ψ ) data for the middle amino acid, n, in the series of tripeptides (n - 1)(n)(n + 1) in six proteins whose three-dimensional structure is known from x-ray studies, (φ,ψ ) values for the ...

These simplified images from Wayne Anderson's lab show how the polypeptide backbone of a Bacillus anthracis protein folds and curls around itself like a ribbon. It is one of 5,617 proteins in the ...

Water-soluble peptides that adopt stable helical conformations are attractive motifs because of their importance in basic science and their broad utility in medicine and biotechnology. Incorporating ...
