Figure 4.

Sequence alignment diagram of the NodB domain of 23 B. anthracis str. Ames and B. cereus str. ATCC14579 PDAs. Numbering is according to Ba0331. Proteins with known tertiary structures have their name coloured purple. Highly conserved residues between the sequences are given in bold letters. Coloured bars show the conserved motifs. The amino acids found in the binding site-forming are boxed in blue, cyan, magenta, yellow, orange, or red colours, respectively. The secondary structure of Ba0331 and Bc1974 is shown on the top and bottom (α-helices as spirals, β-strands as bold arrows, turns as bold T). Diagram using the program ESPRIPT [60].
