2''F-NAD + is a broad-spectrum RNA 2'-phosphotransferase (Tpt1) poison that traps the enzyme on its abortive RNA-2'-phospho-(2''F-ADP-ribose) reaction intermediate

RNA 2'-phosphotransferase Tpt1 catalyzes the removal of an internal RNA 2'-PO4 via a two-step mechanism in which: (i) the 2'-PO4 attacks NAD+ C1'' to form an RNA-2'-phospho-(ADP-ribose) intermediate and nicotinamide; and (ii) transesterification of the ADP-ribose O2'' to the RNA...
