Figure 3From: Crystal structures of Burkholderia cenocepacia dihydropteroate synthase in the apo-form and complexed with the product 7,8-dihydropteroateSequence alignment of three dihydropteroate synthases. The amino acid sequences for DHPS from B. cenocepacia, E. coli and S. aureus are aligned. The secondary structure relating to Bc DHPS is shown colored as in Figure 2. Those residues shaded in black are conserved in all three sequences and grey marks conservation in two of the three.Back to article page
