Figure 5From: Poly-L-glutamate/glutamine synthesis in the cell wall of Mycobacterium bovisis regulated in response to nitrogen availabilityGlnA1 enzyme activity and protein expression of mycobacterial strains in low nitrogen and high nitrogen medium. A. Enzyme activity in the intracellular fractions (black bars) and extracellular fractions (grey bars). ***, ** The p-value given show the statistical significant of the change in GS specific activity between low nitrogen to high nitrogen. P < 0.001 for *** and P < 0.01 for ** was regarded as a statistically significant change in specific activity from low nitrogen to high nitrogen. B. Western blots of the intracellular fractions analyzed by the anti-GS antibodies. LN, low nitrogen; HN, high nitrogen.Back to article page
