Figure 4.
Stereo views of the hydrophobic clusters in the CRT(189–288) structure. The local superpositions of the 20 conformers are for best fit of the backbone atoms N, Cα, and C′ of the following residues: (a) Lys-198, Pro-199, Trp-202, and Trp-272; (b) Lys-215, Pro-216, Trp-219, and Trp-258; (c) Lys-232, Pro-233, Trp-236, and Trp-244. The backbone segments, which do not coincide exactly with those used for the superpositions, are yellow. The amino acid side chains are colored as in Figs. 1 and 2.
