Repeat-proteins are made up of near repetitions of 20- to 40-amino acid stretches. These polypeptides usually fold up into non-globular. elongated architectures that are stabilized by the interactions within each repeat and those between adjacent repeats. but that lack contacts between residues distant in sequence. https://www.jmannino.com/quick-save-Arcade-Smokey-Bear-Belt-p10222-great-pick/
