Cheng, George N. Phillips Jr., and Ronald T. Raines (continued) Cover Illustration: Crystal structure of the A24U/U25A/A46G mutant XPT-PBUX guanine riboswitch aptamer domain in complex with hypoxanthine (Protein Data Bank code: 4fen; Stoddard CD, Widmann J, Trausch JJ, Marcano-Velázquez JG, Knight R, Batey RT. 2013. Nucleotides adjacent to the ligand-binding pocket are linked to activity tuning in the purine riboswitch. J Mol Biol 425: 1596–1611). Image details show riboswitch—ribbon-plate representation, base-specific coloring, A—red, U—magenta, G—green, C—blue; hypoxanthine—spacefilling representation, gray.
