These slides are from 3DSIG 2014, presented on July 11.
I describe our investigation of internal symmetry in protein structures. This is quite common (24% of domains), and has many implications for function, folding, and evolution.
I introduce the CE-Symm method, described in
Myers-Turnbull, D., Bliven, S. E., Rose, P. W., Aziz, Z. K., Youkharibache, P., Bourne, P. E., & Prlić, A. (2014). Systematic Detection of Internal Symmetry in Proteins Using CE-Symm. Journal of Molecular Biology, 426(11), 2255–2268. doi:10.1016/j.jmb.2014.03.010
I discuss the results from running CE-Symm across the PDB, as well as some particularly compelling examples.
