Figure 7: Domain A shows structural similarities to tRNA.
From: Ribosomal small subunit domains radiate from a central core
tRNA is red and domain A is blue. (a) Superimposition of helices 1, 2, and 27 of domain A with tRNA (tRNA is from PDB ID: 4V51)6. Both domain A and tRNA form L-shaped structures. The anticodon stem-loop superimposes on the helix 27 stem-loop. View down the CCA stem of tRNA shows that it is offset from helices 1 and 2 of domain A. (b–d) These views show the 90° rotations on y-axis. (e,f) These views show 180° rotations on x-axis.
