Abstract

A Gram-negative, rod-shaped, non-motile, gamma and UV radiation resistant bacterium Hymenobacter radioresistens DG25B was isolated from a soil sample collected in South Korea. The complete genome sequence of H. radioresistens DG25B consists of one circular chromosome (3,874,646 bp). The bacterium was isolated from gamma ray irradiated soil and contains the genomic features of enzymes involved in the nucleotide excision repair (NER) pathway that protect the damaged DNA. The genome also contains other genes involved in the efficient removal of double-strand breaks (DSB) caused by the ionizing radiations.

Keywords: Hymenobacter; Nucleotide excision repair; Radiation resistance.
