Figure 2From: Novel point mutations attenuate autotaxin activitySubstrate selectivity of H226Q and H434Q. Hydrolyses were detected as described in Methods. Reactions contained 60 ng ATX protein and product accumulation was read beginning at 30 minutes and at intervals thereafter as indicated. A. [LPC] = 125 μM. B. [FS-3] = 6 μM. C. [pNpTMP] = 4 mM. WT: wild type; 420: H420Q; 434: H434Q; 226: H226Q.Back to article page
