Rearrangement of nitrogen fixation genes during heterocyst differentiation in the cyanobacterium Anabaena | | J W Golden

4 Apr 1985 | | Journal: | Nature, 314 (6010), 419-23 | | Abstract: | Nitrogen fixation by the cyanobacterium Anabaena is carried out in heterocysts, specialized, non-dividing cells which differentiate under conditions of ammonia or nitrate deprivation. In Anabaena, heterocyst differentiation is accompanied by rearrangement of some nitrogen fixation genes. A site-specific recombination between an 11 base-pair direct repeat sequence flanking the nifK and nifD genes removes 11 kilobases of intervening DNA, resulting in juxtaposition of the two genes and an alteration of the nifD protein-coding sequence. | | Source: | PubMed, pmid3920531 | | Services: | Forum | Review | Favorites | |
