Abstract:
The nucleotide sequence of the 3' end of the nifU coding sequence, the complete coding sequence of nifH and a substantial part of the 5' end of nifD coding sequence from Nostoc 6720 is presented. The coding sequences are highly conserved with those of Anabaena 7120 and Anabaena sp. L31. However the intergenic region between nifU and nifH contains two segments of short tandemly repetitive repeat sequences (STRRs) that differ from the STRR that is common to both Anabaena7120 and Anabaenasp. L31. Various sequence structures that are common to Nostoc 6720, the Anabaena strains and Plectonema boryanum are discussed.
