Lumazine synthase is an enzyme involved in riboflavin biosynthesis in many, plants and microorganisms, including numerous human pathogens. The fact, that the enzymes of the riboflavin biosynthesis pathway are not present in, the human or animal host makes them potential targets for anti-infective, agents. The crystal structure of lumazine synthase from Candida albicans, was solved by molecular replacement and refined at 2.5-Angstrom, resolution. The results of crystallographic investigations and, sedimentation equilibrium experiments clearly indicated the presence of, pentameric assemblies of the enzyme either in crystals or in solution., Isothermal titration calorimetry measurements of the binding reactions of, four different inhibitors revealed high affinity for all four compounds, with ... | Lumazine synthase is an enzyme involved in riboflavin biosynthesis in many, plants and microorganisms, including numerous human pathogens.

Structural comparison with, previously determined structures of the enzyme.ligand complexes of other, orthologue allowed modeling of the binding of four different inhibitors, into the active site of lumazine synthase from Candida albicans. | ||
