A Comparison of Structural and Evolutionary Attributes of Escherichia coli and Thermus thermophilus Small Ribosomal Subunits: Signatures of Thermal Adaptation
Figure 1
The position of cavities in 16S rRNA and the cavity clustering dendogram is shown.
(Left) The cavities in structurally aligned 16S rRNAs of E. coli (white tube view) and T. thermophilus (not shown) are presented. Cavities are presented as magenta (E. coli) and green (T. thermophilus) spheres. SSCC and non-SSCC cavities are highlighted accordingly. (Right) A part of the dendogram of positional clustering of cavities is presented in linear mode. Notations used in the dendogram: Cavities within 16S rRNAs (RI cavities) were classified into eight groups according to their size: 10–20 Å3 – T1 and E1, 20–30 Å3 – T2 and E2; 30–40 Å3 – T3 and E3, 40–50 Å3 – T4 and E4, 50–70 Å3 – T5 and E5, 70–100 Å3 – T6 and E6, 100–200 Å3 – T7 and E7 and > 200 Å3 – T8 and E8. Along with each cavity, its volume is also shown.
