| Abstract: | Regions of left-handed polyproline II type conformation in globular proteins were studied throughout the PDB bank. The length and sequence of corresponding fragments were analyzed. It was found that a lot of tetrapeptides (from combinatorial possible ones) show the tendency to be included in the left-handed helices. Much more tetrapeptides do not occur in this structure type. |
