Paraburkholderia phytofirmans strain PsJN is a well-studied plant-associated bacterium known to induce resistance against biotic and abiotic stresses. In this work, we described the spontaneous appearance of mucoid variants in PsJN from static cultures. We showed that the conversion from the wild-type (WT) form to variants (V) correlates with an overproduction of EPS...
- Enzymology and Protein Engineering | SpotlightPhosphorothioated DNA Is Shielded from Oxidative Damage
DNA phosphorothioation has been reported in many bacteria. These PT-hosting bacteria live in very different environments, such as the human body, soil, or hot springs. The physiological function of DNA PT modification is still elusive. A remarkable property of PT modification is that purified genomic PT DNA is susceptible to oxidative cleavage. Among the oxidants, hypochlorous acid and H2O2 are of physiological...
