| Outline of Final Research Achievements |
The selenium-resistant bacterium Pseudomonas sp. F2a was isolated from a soil around the selenium accumulation area in India, and its whole genome sequence was revealed using a next-generation sequencer. Based on the genomic information, the genes that may be involved in selenium resistance or selenium reduction ability were identified. Some of the identified genes were cloned and analyzed as purified proteins. In addition, the intermediate of selenite and the reductant protein was analyzed by MS.
