In silico homology modeling (DeepView, http://swissmodel.expasy.org/) of the Burholderia pseudomallei (strain 1026b; DeShazer et al., J. Bacteriol. 179(7):2116-2125) essential Asd protein, using the known Vibrio cholerae Asd structure (Blanco et al., Protein Science 12:27-33) as a template, indicates high homology at the active site. Asd of these two species are much more conserved than compared to the Escherichia coli Asd protein (Hadfield et al. J. Mol. Biol. 289:991-1002).

Abbreviations and Symbols: blue, residues of B. pseudomallei; red, residues of V. cholerae, inhibitor (black, S-methyl-L-cysteine sulfoxide); DAP, diaminopimelic acid; NADP (yellow); and hydrogen bonds (green dashed lines). Amino acid positions are from the B. pseudomallei protein sequence.
