Figure 6From: A nuclear magnetic resonance based approach to accurate functional annotation of putative enzymes in the methanogen Methanosarcina acetivoransConventional 1D 1H NMR spectra showing enzymatic activity of MA3706 in the presence of magnesium chloride. (a) ITP alone at 500 μM concentration; (b) 500 μM ITP mixed with 50 μM MA3706 in the presence of 1 mM magnesium chloride; (c) XTP alone at 500 μM concentration; (d) 500 μM XTP mixed with 50 μM MA3706 in the presence of 1 mM magnesium chloride.Back to article page
