Cover Illustration: Crystal structure of a complex of antitermination factors NusA and NusE with dsRNA (Protein Data Bank code: 3r2d; Stagno JR, Altieri AS, Bubunenko M, Tarasov SG, Li J, Court DL, Byrd RA, Ji X. 2011. Structural basis for RNA recognition by NusB and NusE in the initiation of transcription antitermination. Nucleic Acids Res 39: 7803–7815). Image details show proteins—solid surfaces, NusA—blue, NusE—brown; RNA—ribbon-plate representation, base-specific coloring, A—red, G—green, C—blue, U—magenta.
