Figure 6
The backbone of proteins S7 positioned at its approximate location [as suggested by Mueller & Brimacombe (1997)] in an area showing many of its structural features and the highest density contours of the T30S 7.2 Å map in its vicinity. The map is contoured at 1.5σ, a level chosen for indicating the possible locations of RNA chains, while minimizing the visual interference with the protein location. Highlighted are the amino acids that were found closest to the RNA by crosslinking experiments (Tanaka et al., 1998). |
