Journal ArticleDOI
Accumulation of Mn(II) in Deinococcus radiodurans facilitates gamma-radiation resistance.
Michael J. Daly,Elena K. Gaidamakova,Vera Y. Matrosova,Alexander Vasilenko,Min Zhai,Amudhan Venkateswaran,Matthias Hess,M. V. Omelchenko,Heather M. Kostandarithes,Kira S. Makarova,Lawrence P. Wackett,James K. Fredrickson,Debabrota Ghosal +12 more
TL;DR: It is proposed that Mn(II) accumulation facilitates recovery from radiation injury and exhibits a concentration-dependent response to manganous chloride [Mn(II).
Journal ArticleDOI
Protein Oxidation Implicated as the Primary Determinant of Bacterial Radioresistance
Michael J. Daly,Elena K. Gaidamakova,Vera Y. Matrosova,Alexander Vasilenko,Min Zhai,Richard D. Leapman,Barry Lai,Bruce Ravel,S. W. Li,Kenneth M. Kemner,James K. Fredrickson +10 more
TL;DR: It is presented the case that protein, rather than DNA, is the principal target of the biological action of IR in sensitive bacteria, and extreme resistance in Mn-accumulating bacteria is based on protein protection.
Journal ArticleDOI
Transcriptome dynamics of Deinococcus radiodurans recovering from ionizing radiation
Yongqing Liu,Jizhong Zhou,Marina V. Omelchenko,Alexander S. Beliaev,Amudhan Venkateswaran,Julia Stair,Liyou Wu,Dorothea K. Thompson,Dong Xu,Igor B. Rogozin,Elena K. Gaidamakova,Min Zhai,Kira S. Makarova,Eugene V. Koonin,Michael J. Daly +14 more
TL;DR: Microarray data suggest that DEIRA cells efficiently coordinate their recovery by a complex network, within which both DNA repair and metabolic functions play critical roles, including a predicted distinct ATP-dependent DNA ligase and metabolic pathway switching that could prevent additional genomic damage elicited by metabolism-induced free radicals.
Journal ArticleDOI
Small-Molecule Antioxidant Proteome-Shields in Deinococcus radiodurans
Michael J. Daly,Elena K. Gaidamakova,Vera Y. Matrosova,Juliann G. Kiang,Risaku Fukumoto,Duck-Yeon Lee,Nancy B. Wehr,Gabriela A. Viteri,Barbara S. Berlett,Rodney L. Levine +9 more
TL;DR: By establishing that Mn2+-metabolite complexes of D. radiodurans specifically protect proteins against indirect damage caused by gamma-rays delivered in vast doses, the findings provide the basis for a new approach to radioprotection and insight into how surplus Mn budgets in cells combat reactive oxygen species.
Journal ArticleDOI
How radiation kills cells: Survival of Deinococcus radiodurans and Shewanella oneidensis under oxidative stress
Debabrota Ghosal,Marina V. Omelchenko,Marina V. Omelchenko,Elena K. Gaidamakova,Vera Y. Matrosova,Alexander Vasilenko,Amudhan Venkateswaran,Min Zhai,Heather M. Kostandarithes,Hassan Brim,Kira S. Makarova,Lawrence P. Wackett,James K. Fredrickson,Michael J. Daly +13 more
TL;DR: The hypothesis that Deinococcus radiodurans and other radiation resistant bacteria accumulate exceptionally high intracellular manganese and low iron levels is extended to include consideration of respiration, tricarboxylic acid cycle activity, peptide transport and metal reduction, which together with Mn(II) transport represent potential new targets to control recovery from radiation injury.
