In our lab, a novel enzyme Acetoxcy Drug: Protein Transacetylase (TAase), catalyzing transfer of acetyl group from various polyphenolic peracetate (PA) to certain receptor proteins such as cytochromes P-450, NADPH cytochrome reductase, nitric oxide synthase (NOS) has been established.
Since, a large number of polyphenolic acetates were found to be substrates, the aforementioned enzyme was named Acetoxy drug: protein Transacetylase (TAase).
The earlier work carried out in our laboratory projected PA(s) as irreversible inhibitors of mammalian CYP linked MFO, possibly due to modification of p-450 by way of acetylation catalyzed by acetoxy drug: protein Transacetylase (12-14).
Accordingly, it was hypothesized that the CYP51 of mycobacteria involved in the cell wall sterol synthesis could possibly be modified by our PA(s) through the novel unknown action of GS as transacetylase leading to the death of mycobacterial cells.
