Application
Phosphotransacetylase, from Bacillus stearothermophilus, is used to convert CoA to acetyl CoA. Phosphotransacetylase (pta) is used to study transport systems for acetate. It is used to study metabolic pathways in various bacterium.
Biochem/physiol Actions
Phosphotransacetylase converts CoA to acetyl CoA.
Physical form
Lyophilized powder containing potassium phosphate
Other Notes
One unit will convert 1.0 μmole of CoA to acetyl CoA per min at pH 7.5 at 30 °C using acetyl phosphate as substrate.

Eleven strains of methanogenic bacteria were divided into two groups on the basis of the directionality (oxidative or reductive) of their citric acid pathways. These pathways were readily identified for most methanogens from the patterns of carbon atom labeling in

We report development of a genetic system for making targeted gene knockouts in Clostridium thermocellum, a thermophilic anaerobic bacterium that rapidly solubilizes cellulose. A toxic uracil analog, 5-fluoroorotic acid (5-FOA), was used to select for deletion of the pyrF gene.

Cyclophilins belong to the peptidyl-prolyl cis/trans isomerase family of enzymes (EC 5.2.1.8), which accelerate protein folding by catalysing the cis/trans isomerisation of proline imidic peptide bonds. In the present study, by a combination of bioinformatics methods, we identify phosphate acetyltransferase

Enzymes catalyzing the phosphorolytic cleavage of their substrates can reduce arsenate (AsV) to the more toxic arsenite (AsIII) via the arsenolytic substrate cleavage in presence of a reductant, as glutathione or dithiotreitol (DTT). We have shown this for purine nucleoside
