Because the cell wall envelope of M. tuberculosis is essential for the virus’ viability and virulence, it is the primary target for antimycobacterial drugs. Comprised within the cell wall is mycolic acid, a fatty acid which exists as the free glycolipids trehalose monomycolate (TMM) and trehalose dimycolate (TDM) (Gobec, 2004). It is known that the ag85 complex with its three protein components (A, B, and C) plays a key role in cell wall biosynthesis and the transfer of mycolic acid from one molecule of TMM to another. The resultant molecule, TDM, has been suggested to be important in maintaining M. tuberculosis cell wall integrity. Studies have also suggested that removal of ag85C from a strain of M. tuberculosis results in a significant decrease in the presence of cell-wall linked mycolic acids. Thus, scientists hypothesize that inhibition of ag85C and its mycolyltransferase activity will disrupt TDM and its ability to maintain cell wall integrity (Gobec et al, 2004). Knowing this, researchers have suggested that inhibition of mycolic acid transfer and, ultimately, ag85C, must be involved in the continuously-developing class of antimycobacterial drugs aimed at combatting M. tuberculosis (Belisle et al, 1997).
