DOUBLE COMPLEX OF THE TYROSINE SENSITIVE DAHP SYNTHASE FROM S. CEREVISIAE WITH CO2+, PEP AND THE E4P ANALOGOUE G3P

Overview

3-Deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthases are, metal-dependent enzymes that catalyse the first committed step in the, biosynthesis of aromatic amino acids in microorganisms and plants, the, condensation of 2-phophoenolpyruvate (PEP) and d-erythrose 4-phosphate, (E4P) to DAHP. The DAHP synthases are possible targets for fungicides and, represent a model system for feedback regulation in metabolic pathways. To, gain further insight into the role of the metal ion and the catalytic, mechanism in general, the crystal structures of several complexes between, the tyrosine-regulated form of DAHP synthase from Saccharomyces cerevisiae, and different metal ions and ligands have been determined. The crystal, structures provide evidence that the simultaneous presence of a metal ... [(full description)]
