Figure 1 Evidence of a close fit between the shapes of the intersubunit space and the tRNA molecule. (a) Reconstruction of the ribosome, using a contour that encloses a molecular volume of 4×106Å3. (b) Surface representation of tRNA in an orientation assumed to be likely within the ribosome. AC, anticodon loop; CCA, acceptor end. (c) Cross section through the ribosome reconstruction in the same orientation as depicted in the top panel. The outline of tRNA (b) has been superimposed in green. Landmarks: Small subunit: h, head; sp, spur; cl, cleft. Large subunit: CP, central protuberance; St, L7/L12 stalk; IC, interface canyon.

Figure 2 Topography of the intersubunit space. The ribosome was separated into its two subunits by a cutting plane that roughly divides the intersubunit space in half. Landmarks: small subunit: h, head; sp, spur; cl, cleft. Large subunit: L1, L1 protein; St, L7/L12 stalk; IC, interface canyon; CP, central protuberance. Joint features: CR, central ridge; FB, factor binding region. Biophysical Journal 1998 74, 589-594DOI: (10.1016/S0006-3495(98)77817-8) Copyright © 1998 The Biophysical Society Terms and Conditions

Figure 3 Three main stages of the elongation cycle following the hybrid-site model, shown by using a transparent model of the 70S ribosome (seen from top). (Left) Pretranslocational state, with tRNAs in the A and P sites. (Middle) Hybrid or transitional state, with one tRNA in the P/E state, the other in the A/P state. (Right) Posttranslocational state in which the ribosome is ready for a new ternary complex, aa-tRNA · EF-Tu · GTP, depicting one tRNA in the P site, the other in the E site. (Positions of A and E sites are adopted from Agrawal et al. (1996).) Landmarks in the left-hand panel are defined as in Fig. 2.
