Fig. 1. ThsA cleaves NAD+ into Nam and ADPR.
a NAD+ is degraded by ThsA, but not by ThsB. Data are presented as mean ± SEM for three independent experiments. b LC chromatograms of the NAD+ cleavage products. MS analyses of each chromatographic peak are presented in Supplementary Fig. 2. c ThsA hydrolyzes the Nam–ribosyl bond of NAD+. Molecular weights of NAD+, Nam, and ADPR are indicated in parentheses. d Kinetic parameters of NAD+ cleavage catalyzed by ThsA. Data are presented as mean ± SEM for four independent experiments. Source data are provided as Source Data file.
