Spirosoma radio tolerans is a Gram-negative, short rod-shaped and gamma-radiation-resistant bacterium isolated from rice field in South Korea (GPS; 37 degrees 34'30 '' N, 127 degrees 00'30 '' E). The complete genome of S. radiotolerans consists of a chromosome (7,029,352 bp). From the genome sequence database, we have identified the cluster of genes responsible for DNA recovery from ionizing radiation. The key enzymes for the nucleotide excision repair (NER) were investigated and were identified, suggesting that S. radiotolerans DG5A use (NER) pathways for efficient removal of pyrimidine dimers which are the most abundant type of UV-induced damage. Complete genome information enables further studies on the DNA repair mechanisms during the ionizing radiation. (C) 2015 Elsevier B.V. All rights reserved.
