Our earlier work established a convenient assay procedure for acetoxycoumarin (AC): protein transacetylase (TA) by indirectly quantifying the activity of glutathione (GSH)-S-transferase (GST), the extent of inhibition of GST under the conditions of the assay represented TA activity. In this

Streptococcus pneumoniae among other Gram-positive pathogens produces O-acetylated peptidoglycan using the enzyme OatA. This process occurs through the transfer of an acetyl group from a donor to the hydroxyl group of an acceptor sugar. While it has been established that
A A Frimer et al.

--2-(Dimethylamino) fluorene (1a) and 5-benzoyloxy-2,3,7,8,12,13,17,18-octaethylporphyrin (4) react with superoxide anion radical (generated from KO2/18-crown-6 polyether) in aprotic media. Yet, when incorporated into the lipid bilayer of dimyristoyl phosphatidylcholine liposomes, these two substrates are inert to superoxide, generated enzymatically (xanthine oxidase/acetaldehyde)
H G Raj et al.
Teratogenesis, carcinogenesis, and mutagenesis, 21(2), 181-187 (2001-02-27)
Our earlier studies documented the ability of 7,8-diacetoxy-4-methylcoumarin (DAMC) to cause irreversible inhibition of cytochrome P-450 linked mixed function oxidases (MFO) mediated by membrane bound DAMC: protein transacetylase. Since P-450 catalyzed oxidation of benzene is crucial to its toxic effects
