Figure 9
(a) Ribbon diagram of the HSO b5 domain colored according to temperature factors. Blue represents lower temperature factors and red higher temperature factors. The three residues Pro41, Gly42 and Gly43 with relatively high temperature factors are highlighted by the arrow. The heme is displayed in ball-and-stick representation with the Fe atom in green; the N- and C-termini are labeled. (b) Ellipsoid stereo representation of the anisotropic temperature factors of Pro41, Gly42, Gly43 and the heme and of Pro57 and Phe58 from a symmetry-related molecule. Gly42 and Gly43 display strong anisotropic motion, whereas the surrounding atoms in the heme and symmetry-related residues display mostly isotropic motion. The ellipsoids are contoured at a probability value of 50%. Fig. 9(b) was created with ORTEPIII (Burnett & Johnson, 1996) and Raster3D. (c) Ribbon diagram of CYT b5 color-coded according to temperature factors as described in (a), with Pro40, Gly41 and Gly42 highlighted by the arrow. |
