Electron density maps. (A) Fitted electron density map at 1.06 Å showing the central stretch 21FYYS21 for the final refined structure. (B) Experimental radiation damage-induced phasing (RIP) map with automatically built polyalanine chain obtained from data collected from a mambaquaretin KA crystal that has suffered radiation damage. The 21FYYS21 is easily interpretable and the disulfide Cys5 to Cys55 is clearly visible.
