A second enzyme that removes acetyl groups from lysine residues in E. coli been discovered and represents the founding member of a new enzyme family.

The capacity of Staphylococcus aureus H cell walls to inactivate bacteriophage 52A was lost by removing O-acetyl groups but not by removing ester-linked d-alanine.

amodiaquine is an antimalarial drug used in the prophylaxis and treatment of this disease. however, hepatotoxicity as a life‑threatening adverse effect is associated with its clinical use. we evaluated amodiaquine-induced toxicity in isolated rat hepatocytes as an in vitro model for studying drug‑induced hepatotoxicity. this study attempts to investigate the protective effects of taurine and n-...

a mixture oftrimethylchlorosilane (tms-cl), lithium and tetrahydrofuran (thf) reacts with imines to produce disilyl compound by addition of two trimethylsilyl (tms) groups to the double bond of the imine. on hydrolysis the tms on nitrogen is substituted by hydrogen and yields ? -silylamine. in the presence of acetyl chloride (ch coc1), benzene and pyridine, the ?-silyamine produces the correspo...

Acetylation is a chemical modification for estherification, in which hydroxyl groups are replaced with acetyl groups that offers him major stability, changing the physicochemical and functional properties of the starches. Acetylated starches presents 6-10 ° C less at the gelatinization temperature and the maximum peak viscosity is greater than that of a native starch, so are more readily disper...

In a previous study on heparin biosynthesis, incubation of a mouse mastocytoma microsomal fraction with UDP-N-acetyl-D-glucosamine and UDP-D-glucuronic acid resulted in the formation of two nonsulfated polysaccharides, one of which was fully N-acetylated whereas the other contained about equal amounts of Nacetylated and N-unsubstituted glucosamine residues. In the presence of 3’-phosphoadenylyl...

It has been postulated that triheptanoin can ameliorate seizures by supplying the tricarboxylic acid cycle with both acetyl-CoA for energy production and propionyl-CoA to replenish cycle intermediates. These potential effects may also be important in other disorders associated with impaired glucose metabolism because glucose supplies, in addition to acetyl-CoA, pyruvate, which fulfills biosynth...
