Fig. 4. Stereo view of the superimposition of A.aeolicus Trbp111 (blue) on the anticodon-binding domain of E.coli AspRS (black), looking down the AspRS anticodon-binding pocket. One Trbp111 monomer is shown. Side chains of residues important for tRNA binding are shown in ball-and-stick representation. Conserved AspRS residues important for recognition of anticodon bases (Eiler et al., 1999) are in red. Other, non-conserved residues involved in tRNA binding are in black. Trbp111 residues found important for tRNA binding by mutagenesis experiments are in blue. The figure was made using MOLSCRIPT (Kraulis, 1991).
