Figure 1: SSU rRNA domain architecture, illustrating that four peripheral domains radiate from a central core.
From: Ribosomal small subunit domains radiate from a central core
(a) Secondary structure of the T. thermophilus SSU rRNA colored by domains. Domain A is black, the 5′ domain is yellow, the central domain is red, the 3′ major domain is blue, and the 3′ minor domain is green. (b) Three-dimensional structure of the SSU rRNA (PDB ID 4V51)6. The rRNA is represented in ribbon, except for domain A, which is in space filling representation. The domains in the three-dimensional representation are colored by same scheme as in the secondary structure. (c) Space filling representation of domain A alone. Helix numbers are indicated. (d-f) A series of 90° rotations of the SSU rRNA.
