BIOLOGICAL CHARACTERIZATION OF TWO PUTATIVE DNA METABOLISM ENZYMES IN DEINOCOCCUS RADIODURANS
… to investigate the roles of NurA and HerA in Deinococcus radiodurans, typically studied for its extreme resistance to double-strand DNA breaks. The D. radiodurans genome has homologs of nurA and herA in an operon, and it also has an ftsK gene. We made strains with deletions of either herA or …

Structural studies of putative general stress and related proteins from Deinococcus radiodurans
… stress protein from the extremophilic bacterium Deinococcus radiodurans (R1). The extraordinary ability of D. radiodurans to resist mutation or apoptosis on exposure to high does of ionising radiation has formed the basis of a structural genomics project underway at the European Synchrotron …

The development of Sinorhizobium meliloti and Deinococcus radiodurans as chassis for synthetic biology applications
… meliloti, and the polyextremophile, Deinococcus radiodurans. While some progress has been made toward the development of these chassis, further strain and tool developments are required to unlock their full potential. Here, I present the expansion of the genetic toolkits for S. …

Isolation, reconstitution, and molecular cloning of the manganese-containing superoxide dismutase from Deinococcus radiodurans
… dismutase from a radiation-resistant bacterium Deinococcus radiodurans has been purified to electrophoretic homogeneity. The superoxide dismutase has a specific activity of 3300 units/mg and an apparent molecular mass of 43,000 daltons. The enzyme contains 1.5 gram-atom of manganese per mol …

Residual restoration of DNA lesions in Deinococcus radiodurans mutants indicate presence of a bypass UV-repair process
… and UV-damage repair capability of the Deinococcus radiodurans strains and the hypothesis of a bypass repair system have been investigated. The results obtained provide evidence that UV radiation engenders synergistic effects in combination with other stressors like temperature, …

Electrochemical nanomoulding through proteins
… or "S-layer" proteins, from two organisms---Deinococcus radiodurans and Sporosarcina ureae---were used as the "moulds" for electrochemical fabrication. The proteins are easily purified as micron-sized sheets of periodic molecular complexes with 18-nm hexagonal and 13-nm square unit cell …

Charakterisierung neuer Avilamycin-Derivate und Klinische Studie zur antibiotischen Sequentialtherapie bei Patienten mit Fieber in der Neutropenie
… der grossen ribosomalen Untereinheit von Deinococcus radiodurans, kristallisiert mit Gavibamycin E1, ermöglichten einen Einblick in die Wirkungsweise der Avilamycine. Außerdem konnten Struktur-Wirkungsbeziehungen abgeleitet werden. <br>Neben der Charakterisierung der Avilamycine wurde …

The Role of Bacteroides Conjugative Transposons in the Spread of Antibiotic Resistance Genes, And, The Role of recA in DNA Damage Repair in Deincoccus Radiodurans
… in the extremely radiation resistant organism Deinococcus radiodurans. Previously published studies had suggested that the RecA protein, which is required for repair of DNA damage, from D. radiodurans is unique among RecA proteins and that this uniqueness accounts for this organism's ability to …

Characterization of superoxide dismutase from Actinomyces
… or MnSODs from either Haemophilus influenzae, Deinococcus radiodurans, or S. cerevisiae.

Metronidazole resistance in clinical Bacteroides fragilis isolates from Groote Schuur Hospital, Cape Town, South Africa
… 638Rnim was more closely related to NimA from Deinococcus radiodurans (drNimA) than to any of the other nim genes. Heterologous overexpression of 638Rnim in an Escherichia coli Mtz sensitive mutant resulted in a 3-fold increase in Mtz resistance as compared to the control (6 vs 2 mg/L …

The ecology and evolutionary history of the Deinococcaceae family
Deinococcus radiodurans is the most studied member of the Deinococcaceae family for its outstanding capability to withstand extreme doses of gamma radiation and prolonged desiccation. D. radiodurans is also type species and the first described member of the Deinococcus genus. It demonstrates …
