Figure 8
Close-up views of the ARP/wARP model of CFA synthase built at 2.7 Å resolution using default parameters (red) with the superposed closest homologue (PDB entry 3hem, black): (a) core region of the protein with low sequence variability and well conserved structure, (b) solvent-exposed part where sequence and structure diverge (side chains are not shown for clarity). The final 2Fo − Fc maps are contoured at the 1.5σ density level above the mean. |
