A micromethod for the measurement of acetyl phosphate and acetyl coenzyme A
Analytical Biochemistry, 1980Abstract A method for the determination of acetyl phosphate in cell-free extracts is described. The sensitivity of this method is 20 pmol/ml of extract. An adaptation that permits the measurement of picomole quantities of acetyl CoA is also presented.

Acetylation of nucleosides and acetyl migration
Tetrahedron, 1968Abstract Acetylation of the 2′-OH group predominances over acetylation of the 3′-OH group in derivatives of adenosine, uridine, 3β- d -xylosyluracil and 3β- d -lyxosyluracil. In each case subsequent equilibrium of the products of acetylation results in a net acetyl migration away from the glycosidic link.

Histone Acetylation and Cancer
Acta Oncologica, 2003Acta Oncologica Vol. 42, No. 7, p. 792, 2003Received 7 March 2003Accepted 14 April 2003To the Editor:The organization of chromatin is crucial for the regulation of geneexpression. In particular, both the positioning and properties ofnucleosomes influence promoter-specific transcription in responseto extracellular or intracellular signals (1).

Exchange reaction of acetyl fluoride and acetyl hexafluoroarsenate
Journal of the American Chemical Society, 1969Abstract : From the temperature dependence of the exchange rate of the methyl protons between acetyl fluoride and acetyl hexafluoroarsenate an Arrhenius activation energy of 11.0 kcal/mol and a preexponential factor of 10 to the 8.9 power were obtained.

Nucleosome acetylation sequencing to study the establishment of chromatin acetylation
Analytical Biochemistry, 2014The establishment of posttranslational chromatin modifications is a major mechanism for regulating how genomic DNA is utilized. However, current in vitro chromatin assays do not monitor histone modifications at individual nucleosomes. Here we describe a strategy, nucleosome acetylation sequencing, that allows us to read the amount of modification at ...

[8] Micromethod for the measurement of acetyl phosphate and acetyl coenzyme A
1986The method described here utilizes two enzymes involved with acetyl-CoA and acetyl phosphate metabolism in bacteria to measure these compounds. Basically, the acetyl-CoA and acetyl phosphate in perchloric acid extracts are converted to ATP, in the presence of [3H]ADP of high specific activity, using the enzymes phosphotransacetylase (PTA) and acetate ...

ChemInform Abstract: MOLECULAR STRUCTURES OF ACETYL FLUORIDE AND ACETYL IODIDE
Chemischer Informationsdienst, 1974Abstract The molecular structures of acetyl fluoride and acetyl iodide have been determined by making use of the average distances obtained in the present study together with the moments of inertia reported in the literature. The large amplitude theory for a molecule with an internal top was used in the joint analysis.
