The tyrosine regulated DAHP synthase and the biosynthetic pathway of aromatic amino acids in Saccharomyces cerevisiae
3-Deoxy-D-arabino-Heptulosonat 7-Phosphat (DAHP) Synthasen (EC 2.5.1.54) katalysieren die erste Reaktion des Biosyntheseweges. Das aus der Glykolyse kommende Phosphoenolpyruvat (PEP) und das aus dem Pentosephosphatweg stammende Erythrose-4-Phosphat (E4P) werden zu DAHP kondensiert. In der …

DAHP Synthasen aus Pilzen
… 7-Phosphat. Diese Reaktion wird durch die DAHP Synthase (EC 4.1.2.15) katalysiert. Abhängig vom Organismus handelt es sich hierbei um ein Isoenzym-System von zwei bis drei Enzymen, die entweder unreguliert oder durch jeweils ein Endprodukt, Phenylalanin, Tyrosin oder Tryptophan negativ …

Identification and characterization of a novel class of hydrogen peroxide targets in escherichia coli
… the first enzyme in the shikimic acid pathway (DAHP synthase), which has been shown to have the ability to use Fe2+ as a cofactor, loses activity in Hpx- cells grown in the presence of oxygen. This failure is due to accumulation of damage to DAHP synthase by a Fenton reaction between H2O2 and …

Superoxide stress in Escherichia coli
… (Rpe), peptide deformylase (PDF), and DAHP synthase -- were shown to be inactivated in the Escherichia coli strain which lacks the ability to scavenge O2- (denoted as SOD- mutant). Moreover, the inactivation of DAHP synthase, the first enzyme in the aromatic amino acid biosynthetic …
