On the cover

Crystal structure of a signal sequence bound to the signal recognition particle (Protein Data Bank code: 3ndb; Hainzl T, Huang S, Meriläinen G, Brännström K, Sauer-Eriksson AE. 2011. Structural basis of signal-sequence recognition by the signal recognition particle. Nat Struct Mol Biol 18: 389–391). Image details show proteins—spacefilling representation, SRP 54—green, SRP 19—blue; RNA—ribbon-plate representation, nucleotide-specific coloring, A—red, G—green, C—blue, U—magenta.
