SWAKK
SWAKK is a valuable bioinformatic tool for detecting amino acid sites or regions of a protein under positive selection. It estimates the ratio of non-synonymous to synonymous substitution rates (Ka/Ks) between a pair of protein-coding DNA sequences, by sliding a 3D window, or sphere, across one reference structure. The program displays the results on the 3D protein structure. In addition, for comparison or when a reference structure is unavailable, the web app can also perform a sliding window analysis on the primary sequence.
Browser Requirements
SWAKK is compatible with all major browsers, including Internet Explorer, Firefox, Safari, and Chrome. Javascript must be enabled by the browser.
