Possible Acetylation of Tobramycin CoA Complex by Mycobacterium Tuberculosis
The study where this molecule was obtained is named "Aminoglycoside 2'-N-acetyltransferase from Mycobacterium tuberculosis-Complex with Coenzyme A and Tobramycin". The study suggested a reason for Tobramycin resistance. The resistance may be due to the possible acetylation of mycobacteria by Tobramycin. When Tobramycin acetylates it loses its function. The reason for the acetylation is not fully understood but a possible explanation may be that the mycobacteria needs to be acetylated so that a key biosynthetic intermediate, Mycothiol can be activated. Mycothiol is a major reducing agent in the myobacteria.
If this occurs it may participate in the regulation of cellular redox potential. A redox reaction or reduction-oxidation reaction is a chemical reaction that changes the oxidation state of the atom. An example of this would be the oxidation of a carbon atom to CO2. Oxidation is the loss of electrons or a gain in the oxidation state of the atom or molecule. A reduction is the gain of electrons or the decrease in oxidation state.[1]
