Involvement of pnp in survival of UV radiation in Escherichia coli K-12.

Microbiology (Reading, England) - 1 May 2012

Rath Devashish, Mangoli Suhas H, Pagedar Amruta R, Jawali Narendra

Abstract excerpt

Polynucleotide phosphorylase (PNPase), a multifunctional protein, is a 3'→5' exoribonuclease or exoDNase in the presence of inorganic phosphate (P(i)), and extends a 3'-OH of RNA or ssDNA in the presence of ADP or dADP. In Escherichia coli, PNPase is known to protect against H(2)O(2)- and mitomycin C-induced damage. Recent reports show that Bacillus subtilis PNPase is required for repair of H(2)O(2)-induced...
