Cover illustration: B. subtilis trp RNA-binding attenuation protein (TRAP) complexed with an RNA containing 11 GAG triplets. TRAP is shown as a ribbon with each of the 11 subunits coloured differently. RNA is shown in ball-and-stick representation with the two-nucleotide spacer regions connecting adjacent GAG triplets coloured in white. The activating tryptophan molecules are shown as van der Waals models (p. 615).
