DNA(3′)pp(5′)G de-capping activity of aprataxin: effect of cap nucleoside analogs and structural basis for guanosine recognition
DNA(3′)pp(5′)G caps synthesized by the 3′-PO(4)/5′-OH ligase RtcB have a strong impact on enzymatic reactions at DNA 3′-OH ends. Aprataxin, an enzyme that repairs A(5′)pp(5′)DNA ends formed during abortive ligation by classic 3′-OH/5′-PO(4) ligases, is also a DNA 3′ de-capping enzyme, converting DNA...
