Figure 4From: L-histidine inhibits production of lysophosphatidic acid by the tumor-associated cytokine, autotaxinReaction rate vs. substrate concentration curves in the presence of L-histidine or zinc LPLD determinations were carried out in the presence of 10 mM L-histidine or 0.25 mM Zn++, as indicated. Curves were analyzed with GraphPad Prism (San Diego, CA) to calculate Km and Vmax, as shown.Back to article page
