THE STRUCTURE OF PROTEINS: TWO HYDROGEN-BONDED
HELICAL CONFIGURATIONS OF THE POLYPEPTIDE CHAIN
The title is from the paper by Pauling, Corey, & Branson published in
Proc. Nat'l. Acad. Sci. USA 37 pp. 205-212, (1951).
The pages indexed below are JPEG images of their classic paper. The authors described the structure of the a-helix. More important, they also explained in detail why they excluded other possible structures for the class of proteins they had investigated.
- First page. Introduction
- Second page. Fig. 1 and key peptide features
- Third page. Figs. 2 & 3, the two proposed helices
- Fourth page. Figs. 4 & 5, end views of the helices
- Fifth page. Discussion of the helical features
- Sixth page. Comparison to other proposals and Summary
- Seventh page. End of the references cited
Each page has a JPEG image (480x800, ~100 K) with navigation links and a link to this index page at the bottom.
