Structure of tRNA splicing enzyme Tpt1 illuminates the mechanism of RNA 2′-PO(4) recognition and ADP-ribosylation
Tpt1 is an essential agent of fungal tRNA splicing that removes the 2′-PO(4) at the splice junction generated by fungal tRNA ligase. Tpt1 catalyzes a unique two-step reaction whereby the 2′-PO(4) attacks NAD(+) to form an RNA-2′-phospho-ADP-ribosyl intermediate that undergoes transesterification to...
