Abstract

A Gram-negative, non-motile and short-rod shaped and gamma-radiation-resistant bacterium Deinococcus soli N5(T), isolated from a rice field soil in South Korea. The complete genome of D. soli N5(T) consists of a chromosome (3,236,984bp). The key enzymes for the central DNA repair mechanisms were present in the genome. The enzyme coding genes has been identified which is involving in the nucleotide excision repair (NER) pathway. The gene cluster in the genome sequence suggest that the D. soli N5(T) use (NER) pathways for efficient removal of pyrimidine dimers that are the most abundant type of UV- induced damage.

摘要

一株来自韩国稻田土壤的革兰氏阴性、非运动性、短杆状、抗伽马辐射的细菌 Deinococcus soli N5(T)。D. soli N5(T) 的完整基因组由一条染色体(3,236,984bp)组成。基因组中存在中央 DNA 修复机制的关键酶。已鉴定出参与核苷酸切除修复(NER)途径的酶编码基因。基因组序列中的基因簇表明,D. soli N5(T) 利用(NER)途径有效地去除嘧啶二聚体,嘧啶二聚体是最丰富的紫外线诱导损伤类型。
