Talk:Beta sheet

Super-Secondary Structure?
Being that β sheets are composed of β strands, themselves already secondary structures, could not β sheets be considered supersecondary structure? —Raymond Keller (talk) 00:54, 6 November 2011 (UTC)
 * It is indeed a moot point. But a truly isolated β strand is then not really secondary structure, so usually it is the sheet that is talked about, altho it would be the strand if annotating along the sequence. I'd be fine with adding sheets to a discussion of supersecondary structure, but not with omitting it from secondary structure. - Dcrjsr (talk) 16:22, 4 July 2012 (UTC)

I've reconsidered, and think this is only C class for Biophysics -- a few of the figures are very poor, and the coverage is still rather spotty. Dcrjsr (talk) 00:12, 14 July 2012 (UTC)

Update to Dynamic features
This update has been challenged as COI please weigh in.

Beta-sheets in proteins are thought to carry out low-frequency accordion-like motion as observed by the Raman spectroscopy and analyzed with the quasi-continuum model.

The beta-barrel protein GFP has been shown by neutron scattering to undergo collective motions of adjacent chains at ~1 THz. These motions are thought reflect local rigidity within proteins, revealing beta structures to be generically more rigid than alpha or disordered proteins.

 * If you read our content policies, WP:OR and WP:NPOV, and our guidelines for sources, WP:RS and WP:MEDRS, you will see that all of them strongly urge editors to use secondary sources. There are many many reasons why this is best practice.  What is your reason for wanting to use primary sources at all, and these primary sources in particular?   Also, based on your editing behavior, Boghog warned you that you may have a COI (as we consider WP:COI) and warned you to be careful to avoid WP:SELFCITE.  So - are you citing your own research, or not?   Please answer those three questions.  Thanks.Jytdog (talk) 00:31, 21 February 2015 (UTC)
