title: Cloning and nucleotide sequence of the gene for dinitrogenase reductase (nifH) from the heterocyst-forming cyanobacterium Anabaena sp. L31.
abstract: The nucleotide sequence of an 1655 base pair segment from Anabaena sp. L31 containing the 3' half of the nifU gene, the complete sequence of the nifH gene and the 5' end of the nifD gene is presented. nifH is very highly conserved with the same gene from Anabaena sp. PCC 7120 (91% identical at the nucleotide level; 94% identical at the amino acid level) as are nifU and nifD. The intergenic regions are less well conserved.
