In detail, the scientists used coupled high-resolution mass spectrometry to obtain precise insights into the inhibition mechanism and discovered that 7dSh blocks DHQS (Dehydroquinatesynthase), an enzyme of the shikimate
Lactofen increases glyphosate-simulated shikimate
production in little mallow (Malva parviflora).
New Insights into the shikimate
and aromatic amino acids biosynthesis pathways in plants.
Rataj et al., "Caffeoyl shikimate
esterase (CSE) is an enzyme in the lignin biosynthetic pathway in arabidopsis," Science, vol.
These were Isocitrate dehydrogenase (Idh1, Idh2), Malic enzyme (Mel, Me2), and Shikimate
dehydrogenase (Skdh) that were resolved in a buffer morpholine-citric system pH 7.5 (Ranker et al., 1989), which was run at a constant current of 25 mA for about 6 h.
The seven genes are: arc (carbamate kinase), aroE (shikimate
dehydrogenase), glpF (glycerol kinase), gmk (guanylate kinase), pta (phosphate acetyl transferase), tpi (triosephosphateisomerase), yqiL (acetyl coenzyme A acetyl transferase).
Bacteria and plants make three complex amino acids (we call them "aromatic amino acids") in a small biochemical pathway called the "Shikimate
Pathway." One of the enzymes of that pathway is called "EPSPS" for short.
While PEPCase plays a role in C4 plants for the CO2 assimilation that produces carbohydrate, EPSPS functions in the shikimate
pathway that produces the aromatic amino acids and many aromatic secondary metabolites (Herrmann, 1995).
The efficacy of this herbicide on red rice control resulted from its alternative mode of action, inhibiting 5-enolpyruvylshikimate 3- phosphate synthase (EPSPS), a key enzyme in the shikimate
biosynthetic pathway that is necessary for the production of the aromatic amino acids, auxin, phytoalexins, folic acid, lignin, plastoquinones and many other secondary products.
aureus as described previously, including carbamate kinase (arcC), shikimate
dehydrogenase (aroE), glycerol kinase (glp), Guanylate kinase (gmk), phosphate acetyltransferase (pta), triosephosphate isomerase (tpi), and acetyl coenzyme A acetyltransferase (yqi).
Allelopathic agents reported from higher plants include coumarins, flavonoids, alkaloids, tannins, certain quinones, hydroxamic acids, sesquiterpene lactones, and various mono-, sesqui-, di-, and triterpenes, among other compounds, synthesized from either the acetate or the shikimate
Shikimic acid, commonly known as its anionic form shikimate
, is a cyclohexene, a cyclitol and a cyclohexanecarboxylic acid.
