Table 2. kinact/KI Values for Compounds 12a–e, 18, and 24a.
kinact/KI was determined using six concentrations of inhibitor at five different time points. kinact/KI was calculated from linear fit of kobs obtained from two replicates.
kinact/KI was calculated from nonlinear regression of kobs obtained from two replicates. kobs = kinact/KI because [I] ≪ KI. Cl-amidine under the assay conditions reported here gave the following kinact/KI values: PAD1, 4550 ± 860; PAD2, 520 ± 50; PAD3, 2340 ± 80; PAD4, 1770 ± 470.23 See Supporting Information for further assay details.
