strain MN05-02 is a UV-resistant bacterium isolated from a manganese deposit in the Sonoran Desert, Arizona, USA. The LD of this strain is 123 Jm, which is twice that of , and therefore can be a useful resource for comparative study of UV resistance and the role of manganese on this phenotype. Its complete genome is comprised of a chromosome of 3,488,433 bp and a plasmid of 154,991 bp. The chromosome contains 3,430 putative genes, including 3,366 protein coding genes, 52 tRNA and 12 rRNA genes. Carotenoid biosynthesis operon structure coded within the genome mirrors the characteristic orange-red pigment this bacterium produces, which presumably partly contribute to its UV resistance.
菌株MN05 - 02是从美国亚利桑那州索诺兰沙漠的一个锰矿床中分离出的一种抗紫外线细菌。该菌株的致死剂量为123 J/m²，是[此处原文缺失对比菌株]的两倍，因此可作为抗紫外线及锰对该表型作用的比较研究的有用资源。其完整基因组由一条3,488,433 bp的染色体和一条154,991 bp的质粒组成。该染色体包含3,430个推定基因，其中包括3,366个蛋白质编码基因、52个tRNA基因和12个rRNA基因。基因组中编码的类胡萝卜素生物合成操纵子结构反映了该细菌产生的特征性橙红色色素，这可能部分有助于其抗紫外线能力。
