Nitrate assimilation gene cluster from the heterocyst-forming cyanobacterium Anabaena sp. Strain PCC 7120
(American Society for Microbiology, 1997)
A region of the genome of the filamentous, nitrogen-fixing, heterocyst- forming cyanobacterium Anabaena sp. strain PCC 7120 that contains a cluster of genes involved in nitrate assimilation has been identified. The genes ...

Transfer of a genetic marker from a megaplasmid of Anabaena sp. strain PCC 7120 to a megaplasmid of a different Anabaena strain
(American Society for Microbiology, 1994)
The 410-kb α megaplasmid of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 was found to bear the nucA gene that encodes a sugar-nonspecific nuclease. That gene was mutated by insertion of a cassette ...

The narA locus of Synechococcus sp. strain PCC 7942 consists of a cluster of molybdopterin biosynthesis genes
(American Society for Microbiology, 1998)
The narA locus required for nitrate reduction in Synechococcus sp. strain PCC 7942 is shown to consist of a cluster of genes, namely, moeA, moaC, moaD, moaE, and moaA, involved in molybdenum cofactor biosynthesis. The ...

Amino Acid Transport in Taxonomically Diverse Cyanobacteria and Identification of Two Genes Encoding Elements of a Neutral Amino Acid Permease Putatively Involved in Recapture of Leaked Hydrophobic Amino Acids
(American Society for Microbiology, 1997)
The activities of uptake of thirteen 14C-labeled amino acids were determined in nine cyanobacteria, including the unicellular strains Synechococcus sp. strain PCC 7942 and Synechocystis sp. strain PCC 6803; the filamentous ...

Amino acid transport systems required for diazotrophic growth in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 1995)
Uptake of 16 amino acids by the filamentous, heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 was characterized with regard to kinetic parameters of transport, intracellular accumulation of the transported ...
