expression of a fusion of genes pchA and pchB from Pseudomonas aeruginosa, which encode isochorismate synthase and isochorismate pyruvate-lyase, in Arabidopsis thaliana, with targeting of the gene product either to the cytosol, c-SAS plants, or to the chloroplast, p-SAS plants. In p-SAS plants, the amount of free and conjugated SA is increased more than 20fold above wild type level. P-SAS plants show a strongly dwarfed phenotype and produce very few seeds. Targeting of SAS to the cytosol causes a slight increase in free salicylic acid and a significant threefold increase in conjugated salicylic acid. The modest increase in total salicylic content does not strongly induce the resistance marker PR-1, but results in enhanced disease resistance towards a virulent isolate of Peronospora parasitica. Increased resistance of c-SAS lines is paralleled with reduced seed production |

alternative computational rational approach to improve the secondary catalytic activity of enzymes, taking as a test case the IPL enzyme. The approach is based on the use of molecular dynamic simulations employing hybrid quantum mechanics/molecular mechanics methods that allow describing breaking and forming bonds |

| 4.2.99.21 | drug development |
enzyme MbtI represents an appealing target for development of inhibitors of mycobactin biosynthesis since it is structurally and biochemically characterized, has no human orthologues, and is conditionally essential under iron-deficient conditions. Inhibitors are designed against the isochorismatase activity of the enzyme (EC 5.4.4.2) |
