Figure 5
(a) Comparison of the known transmembrane helical structure of MscL (red) and the model derived from ab initio molecular replacement (blue). (b) View perpendicular to the membrane normal. (c) Ribbon representation of the known MscL structure. (d) Ribbon representation of the transmembrane and cytoplasmic helices built by ARP/wARP HelixBuild into electron density computed with phases from ab initio molecular replacement. This figure was prepared with PyMOL (DeLano Scientific, San Carlos, CA, USA) and POVSCRIPT (Fenn et al., 2003; Kraulis, 1991) |
