Structural and functional importance of theβ-turn in proteins. Studies on proline-containing peptides

We report here two sets of results on proline-containing linear peptides, one of which brings out the role of theβ-turn conformation in the structure of nascent collagen while the other points to the functional importance of the β-turn in calcium-binding proteins. Based on the data on peptides containing the -Pro-Gly-sequence, we had proposed and experimentally verified that theβ-turn conformation in these peptides is a structural requirement …
