Desthiobiotin (DTB)-modified and TAMRA-modified 2''OMeNAD+ are RNA 2'-phosphotransferase (Tpt1) poisons that enable affinity-tagging and fluorescence-tagging of internal RNA 2'-phosphate groups
{{output}}
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 A... ...
