Figure 4From: Comparison of Mycobacterium tuberculosis isocitrate dehydrogenases (ICD-1 and ICD-2) reveals differences in coenzyme affinity, oligomeric state, pH tolerance and phylogenetic affiliationActivity of M. tb ICDs decrease at higher salt concentration. Activity of the enzymes ICD-1 (a) and ICD-2 (b) was measured by reduction of NADP at different concentrations of NaCl. The enzymes were active in presence of 200 mM NaCl above which the activity rapidly decreases.Back to article page
