Fold: DNA-binding pseudobarrel domain
Hi, what do You think about "Fold: DNA-binding pseudobarrel domain "? Should we put "open barrel fold" into this article? Cheers. Redeemer079 (talk) 20:19, 24 March 2008 (UTC)

I see that the "OB fold" is one of the top ten folds that are found. Its occurrence is 3.7%, compared to 4.3% for the TIM barrel. (from "The Protein Chart", Garrett, R. C. & Orengo, C. A. Published by Wiley-VCH, 2008.) I suggest giving it a separate page, since the TIM barrel has a separate page. --Christopher King (talk) 17:25, 1 January 2009 (UTC)

Beta-barrels in proteins may carry out low-frequency breathing-like motion as observed by the Raman spectroscopy and analyzed with the quasi-continuum model. In fact, the beta-barrel protein GFP has been shown by neutron scattering to undergo collective motions at ~1 THz. These motions are thought to be sensitive to local rigidity within proteins, revealing beta structures to be generically more rigid than alpha or disordered proteins.

For more about the low-frequency collective motions in biomacromolecules and its biological function, see low-frequency collective motion in proteins and DNA. — Preceding unsigned comment added by Jon33dn (talk • contribs) 23:48, 20 February 2015 (UTC)
