Crystal structure of P. aeruginosa dihydropyrimidinase. (a) Ribbon diagram of a P. aeruginosa dihydropyrimidinase tetramer. Each P. aeruginosa dihydropyrimidinase monomer is color-coded. Two zinc ions in the active site are presented as black spheres. (b) Ribbon diagram of a P. aeruginosa dihydropyrimidinase monomer with the secondary structures labeled.
