應用
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.
生化／生理作用
Phosphotransacetylase converts CoA to acetyl CoA.
單位定義
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

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
