Antifungal Compounds from Cyanobacteria
Marine Drugs, 2015 Cyanobacteria are photosynthetic prokaryotes found in a range of environments. They are infamous for the production of toxins, as well as bioactive compounds, which exhibit anticancer, antimicrobial and protease inhibition activities.

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 ...

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.

Heterocyst and Nitrogenase Development in Anabaena cylindrica [PDF]
Journal of General Microbiology, 1976 The differentiation of filaments of a continuous culture of Anabaena cylindrica after removal of fixed nitrogen has been examined. Rapid development of proheterocysts (4-5 h) and mature heterocysts (14 h) in an ordered sequence was observed; the development of the latter was concomitant with the onset of nitrogenase activity. Commitment times of 2-3 h (
