<p>The FGD activity was assessed for Rv0132c–Δ38 protein and <i>Mtb</i>–FGD1 as a positive control. <i>Mtb</i>–FGD1 shows a decrease at 420 nm absorbance (green and red lines), whereas Rv0132c–Δ38 protein indicated no change in the absorbance (yellow and blue lines). The same results were observed using various concentrations of Rv0132c–Δ38 protein in the presence of different concentrations of glucose-6-phpsphate. The graph shows assays containing 1 µM of each enzyme, 25 µM F<sub>420</sub> with 0.1 mM (green and yellow lines) and 1 mM (red and blue lines) glucose-6-phosphate.</p
