Characterization and distribution of IS8301 in the radioresistant bacterium Deinococcus radiodurans.
Deinococcus radiodurans RNA ligase (DraRnl) seals 3΄-OH/5΄-PO4 nicks in duplex nucleic acids in which the 3΄-OH nick terminus consists of two or more ribonucleotides. DraRnl exemplifies a widely distributed Rnl5 family of nick-sealing RNA ligases, the physiological functions of which are uncharted. Here we show via gene knockout that whereas DraRnl is inessential for growth of D. radiodurans, i...
Most prokaryotes require Asp-tRNA(Asn) for the synthesis of Asn-tRNA(Asn). This misacylated tRNA species is synthesized by a non-discriminating aspartyl-tRNA synthetase (AspRS) that acylates both tRNA(Asp) and tRNA(Asn) with aspartate. In contrast, a discriminating AspRS forms only Asp-tRNA(Asp). Here we show that a conserved proline (position 77) in the L1 loop of the non-discriminating Deinoc...
