Mutant derivatives of EcFtsZ and thermal factor analysis of MtbFtsZ and MjFtsZ structures. (A) Ribbon representation of EcFtsZ, showing the amino (light gray) the carboxyl (blue) domains. (Red balls and sticks) Point mutations; (yellow sticks) nucleotides. (B) Bar plot of the average normalized B-factor versus secondary structural element in MjFtsZ (black bars) and MtbFtsZ (white bars). The normalized B-factor was calculated by the equation B norm = (Bi − B min)/(B max − Bmin), where Bi is the B-factor for Cα of the ith amino acid, and B min and B max are the minimum and maximum value of Cα B-factor in the protein, respectively. Secondary structural elements were labeled according to Oliva et al. (2004). Protein representation was made using the DS Modeling v1.1 package (Accelrys) and PovRay 3.6 (Persistence of Vision Raytracer Pty. Ltd.).
