Chorismate synthase (CS) catalyses the conversion of 5-enolpyruvylshikimate 3-phosphate (EPSP) to form chorismate, which is the last common intermediate in the synthesis of the three aromatic amino acids phenylalanine, tyrosine and tryptophan. Despit

Activities of all chorismate synthases (CS) so far analyzed are absolutely dependent upon reduced flavin. For monofunctional CSs, which represent the only class of CSs that have yet been cloned, the flavin must be reduced either (photo-)chemically or

Potato (Solanum tuberosum L.) cells were transformed with an antisense DNA construct encoding part of 3-deoxy-D-arabino-heptulosonate-7-phosphate (DAHP) synthase (EC 4.1.2.15), the first enzyme of the shikimate pathway, to examine the role(s) of this

Coding regions of a cDNA for precursor and mature chorismate synthase (CS), a plastidic enzyme, from Corydalis sempervirens were expressed in Escherichia coli as translational fusions to glutathione-S-transferase. Fusion proteins were purified, and p

In alpha 1-antitrypsin deficiency in humans, inadequately regulated activity of serine protease activity is responsible for the chronic lung tissue degeneration and irreversible loss of pulmonary function seen in those individuals with emphysema. Typ

Three plastidic chorismate synthase isozymes (CS1, CS2 and CS2 delta) of tomato were identified by isolation of the corresponding cDNAs. These three cDNAs are derived from only two genes (LeCS1 and LeCS2). This additional complexity results from diff

Tomato (Lycopersicon esculentum L. cv. UC82b) was found to contain two distinct 3-deoxy-D-arabino-heptulosonate 7-phosphate (DAHP) synthase genes that are differentially expressed. The corresponding cDNAs were isolated and characterized. Both genes c

The first enzyme of the shikimate pathway, 3-deoxy-D- arabino -heptulosonate-7-phosphate synthase (EC 4.1.2.15), is induced by wounding potato or tomato tissue. The increase in enzyme activity is associated with elevated amounts of the enzyme as dete

The contribution of wound-ethylene to wound-induced gene expression was investigated in unripe tomato pericarp using inhibitors of ethylene action. Wounded unripe tomato pericarp was treated with 2,5-norbornadiene or silver thiosulfate to inhibit spe
