Single-Stranded DNA Transposition Is Coupled to Host Replication
DNA transposition has contributed significantly to evolution of eukaryotes and prokaryotes. Insertion sequences (ISs) are the simplest prokaryotic transposons and are divided into families on theExpand

Irradiation-Induced Deinococcus radiodurans Genome Fragmentation Triggers Transposition of a Single Resident Insertion Sequence
Stress-induced transposition is an attractive notion since it is potentially important in creating diversity to facilitate adaptation of the host to severe environmental conditions. One common majorExpand

Identification of New Genes Contributing to the Extreme Radioresistance of Deinococcus radiodurans Using a Tn5-Based Transposon Mutant Library
Here, we have developed an extremely efficient in vivo Tn5-based mutagenesis procedure to construct a Deinococcus radiodurans insertion mutant library subsequently screened for sensitivity toExpand

Expression of the trxA gene for thioredoxin 1 in Rhodobacter sphaeroides during oxidative stress
Expression of the thioredoxin (trxA) gene of Rhodobacter sphaeroides is regulated by oxidative stress at the transcriptional and post-transcriptional levels. All oxidative stress agents testedExpand

Thioredoxin is essential for Rhodobacter sphaeroides growth by aerobic and anaerobic respiration.
To investigate the biological role of thioredoxin in the facultative photosynthetic bacterium Rhodobacter sphaeroides, attempts were made to construct a thioredoxin-deficient mutant by site-specificExpand

DNA recognition and the precleavage state during single‐stranded DNA transposition in D. radiodurans
Bacterial insertion sequences (ISs) from the IS200/IS605 family encode the smallest known DNA transposases and mobilize through single‐stranded DNA transposition. Transposition by one particularExpand

ISDra2 transposition in Deinococcus radiodurans is downregulated by TnpB
Transposable elements belonging to the recently identified IS200/IS605 family radically differ from classical insertion sequences in their transposition mechanism by strictly requiringExpand

Thioredoxin can influence gene expression by affecting gyrase activity.
The expression of many genes of facultatively photosynthetic bacteria of the genus Rhodobacter is controlled by the oxygen tension. Among these are the genes of the puf and puc operons, which encodeExpand

DdrI, a cAMP Receptor Protein Family Member, Acts as a Major Regulator for Adaptation of Deinococcus radiodurans to Various Stresses.
The DNA damage response ddrI gene encodes a transcription regulator belonging to the cAMP receptor protein (CRP) family. Cells devoid of the DdrI protein exhibit a pleiotropic phenotype, includingExpand

Expression of the thioredoxin gene (trxA) inRhodobacter sphaeroides Y is regulated by oxygen
The structural gene (trxA) coding for thioredoxin in the photosynthetic bacteriumRhodobacter sphaeroides has been cloned and sequenced previously. In the present study, the role of oxygen intrxAExpand
