A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium [PDF]
, 2017 Heterocystous cyanobacteria such as Nostoc sp. are filamentous photosynthetic organisms that, in response to nitrogen deficiency, undergo a differentiation process transforming certain, semi-regularly spaced cells into heterocysts, devoted to nitrogen ...

Characterization of a chromosomal type II toxin-antitoxin system mazEaFa in the Cyanobacterium Anabaena sp. PCC 7120. [PDF]
PLoS ONE, 2013 Cyanobacteria have evolved to survive stressful environmental changes by regulating growth, however, the underlying mechanism for this is obscure. The ability of chromosomal type II toxin-antitoxin (TA) systems to modulate growth or cell death has been ...

Characterization of TrxC, an Atypical Thioredoxin Exclusively Present in Cyanobacteria [PDF]
, 2018 Cyanobacteria form a diverse group of oxygenic photosynthetic prokaryotes considered to be the antecessor of plant chloroplast. They contain four different thioredoxins isoforms, three of them corresponding to m, x and y type present in plant chloroplast,

Localization of an Uptake Hydrogenase in Anabaena [PDF]
Plant Physiology, 1978 Occurrence and localization of an uptake hydrogenase were examined in three strains of the blue-green alga, Anabaena. In vivo H(2) uptake was detected (0.60-1.44 mumoles/[mg of chlorophyll a per hour]) in all three strains when grown with N(2) as the sole source of nitrogen.

Glutamine and glutamate transport by Anabaena variabilis [PDF]
Journal of Bacteriology, 1983 Anabaena variabilis, a dinitrogen-fixing cyanobacterium, has high- and low-affinity systems for the transport of glutamine and glutamate. The high-affinity systems have Km values of 13.8 and 100 microM and maximal rates of 13.2 and 14.4 nmol X min-1 X mg of chlorophyll a-1 for glutamine and glutamate, respectively.
