Figure 1. Figure 1. Electron Density for the First Trimer of RNA Bound in the Methyltransferase Active SiteThe 2.7 Å density is calculated as a 2F[o] − F[c] map using only the protein model to calculate the phases. Contoured at 1σ, only the density near the RNA is displayed for clarity. The surrounding atoms of the protein are shown without density for context. This figure was rendered using RIBBONS ([5]).
