Nonenzymatic acetylation of histones with acetyl-CoA
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1970Abstract 1. When purified calf thymus histones were incubated with [1-14C]acetyl-CoA and treated to remove the acid-soluble fraction with trichloroacetic acid, a large amount of radioactivity still remained in the 15 % trichloroacetic acid-insoluble precipitate. 2.

Psychopharmacology, 1979
Microsome-free preparations of rodent and human liver were shown to contain N-acetyl transferase from experiments using procainamide as substrate. These preparations then acetylated phenelzine from the quantitative transfer of radiolabeled acetate. This in vitro demonstration of phenelzine acetylation in rodent and human liver was corroborated by the ...

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.

Acetylation of Sulphanilamide by Acetyl Metaphosphate
Nature, 1950THE problem regarding the nature of the reactive, intermediate C2-compound in acetate metabolism is not clear at present. With regard to biological acetylations, it is evident, especially from Lipmann's1 work, that a strongly acetylating substance is formed in an enzymatic reaction between acetate and adenosine triphosphate.

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.

Sulphamethoxazole acetylation in fast and slow acetylators.
International journal of clinical pharmacology, therapy, and toxicology, 1990Acetylation of sulphamethoxazole was studied in 22 subjects previously phenotyped with sulphadimidine. Sulphamethoxazole and its acetylated metabolite were measured in 6 h plasma and 0-6 h urine samples. Percentage of plasma acetylated-sulphamethoxazole did not correlate with the percentage of urinary acetylated-sulphamethoxazole.
