Figure 4From: Crystal structures of Burkholderia cenocepacia dihydropteroate synthase in the apo-form and complexed with the product 7,8-dihydropteroateThe variations in the positions of active site loops across three DHPS structures. Superposition of the structures of Bc DHPS with 7,8-dihydropteroate bound (blue), Ec DHPS with 7,8-dihydropterin pyrophosphate bound (green, [PDB ID: 1AJ2]) and Sa DHPS with 6-hydroxymethylpterin-diphosphate bound (violet, [PDB ID: 1AD4]).Back to article page
