Deinococcus radiodurans HD-Pnk, a Nucleic Acid End-Healing Enzyme, Abets Resistance to Killing by Ionizing Radiation and Mitomycin C.

Journal of bacteriology - 1 Sept 2018

Schmier Brad J, Shuman Stewart

Abstract excerpt

5'- and 3'-end healing are key steps in nucleic acid break repair in which 5'-OH and 3'-PO4 or 2',3'-cyclic-PO4 ends are converted to 5'-PO4 and 3'-OH termini suitable for sealing by polynucleotide ligases. Here, we characterize Deinococcus radiodurans HD-Pnk as a bifunctional end-healing enzyme composed of N-terminal HD (histidine-aspartate) phosphoesterase and C-terminal P-loop polynucleotide kinase (Pnk)...
