5-enol-Pyruvyl-Shikimate-3-Phosphate Synthase from Zea mays Cultured Cells (Purification and Properties)

Purification and Properties of 5-Enolpyruvylshikimate-3-Phosphate Synthase from Dark-Grown Seedlings of Sorghum bicolor.

5-Enolpyruvylshikimate-3-phosphate (EPSP) synthase (3-phospho-shikimate 1-carboxyvinyltransferase; EC 2.5.1.19) was purified 1300-fold from etiolated shoots of Sorghum bicolor (L.) Moench. Native polyacrylamide gel electrophoresis revealed three barely separated protein bands staining positive for EPSP synthase activity. The native molecular weight was determined to be 51,000. Enzyme activity w...

Glyphosate Inhibition of 5-Enolpyruvylshikimate 3-Phosphate Synthase from Suspension-Cultured Cells of Nicotiana silvestris.

Treatment of isogenic suspension-cultured cells of Nicotiana silvestris Speg. et Comes with glyphosate (N-[phosphonomethyl]glycine) led to elevated levels of intracellular shikimate (364-fold increase by 1.0 millimolar glyphosate). In the presence of glyphosate, it is likely that most molecules of shikimate originate from the action of 3-deoxy-d-arabino-heptulosonate 7-phosphate (DAHP) synthase...

Purification and properties of 3-hexulose phosphate synthase and phospho-3-hexuloisomerase from Methylococcus capsulatus.

3-Hexulose phosphate synthase and phospho-3-hexuloisomerase were purified 40- and 150-fold respectively from methane-grown Methylococcus capsulatus. The molecular weights of the enzymes were approximately 310000 and 67000 respectively, as determined by gel filtration. Dissociation of 3-hexulose phosphate synthase into subunits of molecular weight approx. 49000 under conditions of low pH or low ...

Progress in cloning, expression and purification of 5-enolpyruvylshikimate-3-phosphate synthase from pathogens causing meningitis.

Expression, purification and properties of shikimate dehydrogenase from Mycobacterium tuberculosis.

Tuberculosis, caused by Mycobacterium tuberculosis, continues to be one of the main diseases to mankind. It is urgent to discover novel drug targets for appropriate antimicrobial agents against this human pathogen. The shikimate pathway is considered as an attractive target for the discovery of novel antibiotics for its essentiality in bacteria and absence in mammalian cells. The Mycobacterium ...
