Effects of DNA(3′)pp(5′)G capping on 3′ end repair reactions and of an embedded pyrophosphate-linked guanylate on ribonucleotide surveillance
When DNA breakage results in a 3′-PO(4) terminus, the end is considered ‘dirty’ because it cannot prime repair synthesis by DNA polymerases or sealing by classic DNA ligases. The noncanonical ligase RtcB can guanylylate the DNA 3′-PO(4) to form a DNA(3′)pp(5′)G(OH) cap. Here we show that DNA capping...
