3-10 Helix | Pi Helix | Helical Structures in Proteins (Part2) | Dr. Nagendra Singh | PENS#65

After Alpha helix 3-10 helix is most common helical structure found in proteins. In this lecture we have discussed detailed features of 3-10 helic and Pi helix along with their comparisons with alpha helix.
A 310 helix is a type of secondary structure found in proteins and polypeptides. Of the numerous protein secondary structures present, the 310-helix is the fourth most common type observed; following α-helices, β-sheets and reverse turns. 310-helices constitute nearly 10–15% of all helices in protein secondary structures, and are typically observed as extensions of α-helices found at either their N- or C- termini. Because of the α-helices tendency to consistently fold and unfold, it has been proposed that the 310-helix serves as an intermediary conformation of sorts, and provides insight into the initiation of α-helix folding.

The Lectures are given Dr. Nagendra Singh aiming to spread basic understanding and awareness of biological molecules and reactions. Dr. Nagendra Singh finished his Doctoral and Post Doctoral studies from "All India Institute of Medical Sciences" (AIIMS) New Delhi. Dr. Singh has a vast experience of research and Teaching in the fields of Structure & Molecular Biology and Biochemistry, which also include Biomolecules, Proteomics, Protein Engineering and Drug Design.

Where is polyproline helices found in biological systems?
