Benzo[d]thiazole-2-carboxamides as New anti-TB Chemotypes Inhibiting Mycobacterial ATP Phosphoribosyl Transferase (HisG) - Supplementary Material

Figure 1. Role of ATP-PRTase enzyme in the first step of cycle of biosynthesis of L-Histidine.

Figure 2. The SDS-PAGE (sodium dodecyl-sulfate polyacrylamide gel electrophoresis) profile of purified recombinant ATPPRTase

from the complexed mixture of proteins.

Figure 3. The plots of velocity of enzymatic reaction versus concentration of ATP (A) and PRPP (B). The Michaelis-Menten constant

for PRPP and ATP were observed with values of 72 ± 15 and 238 ± 28 μM, respectively with the value of Vmax of 5.1 ± 1.3 μM min-.
