| Research Abstract |
It has been clarified that the purple photosynthetic bacterium, Rubrivivax gelatinosus, has, at least, five electron carrier proteins potentially working as electron donors to the photochemical reaction center complex. One of them, the most recently found, was a mono-heme cytochrome c, which was identified as NirM included in the nitrite reduction pathway, based on the genome analysis on this bacterium. This shows that electron carriers included in photosynthesis and nitrite reduction are phylogenetically related. It has been also shown that a mutant strain synthesizing a large amount of NirM acquires a high ability in nitrite consumption under the photosynthetic growth conditions.
