Mutual dependence of the expression of the cell differentiation regulatory protein HetR and the global nitrogen regulator NtcA during heterocyst development [PDF]
, 2002 Heterocyst differentiation in the cyanobacterium Anabaena sp. strain PCC 7120 depends on both the global nitrogen regulator NtcA and the cell differentiation regulatory protein HetR, and induction of hetR upon nitrogen step-down depends on NtcA.

Growth Characteristics of an Estuarine Heterocystous Cyanobacterium
Frontiers in Microbiology, 2017 A new estuarine filamentous heterocystous cyanobacterium was isolated from intertidal sediment of the Lagoa dos Patos estuary (Brazil). The isolate may represent a new genus related to Cylindrospermopsis.

Protein Phosphorylation and a Novel Phosphatase in the Cyanobacterium Anabaena [PDF]
, 2008 The focus of this paper is a dual-specific protein phosphatase (DSP) previously found in the periplasm of the cyanobacterium Anabaena PCC 7120 that may regulate circadian rhythms in that organism. To fully understand the topic, summaries of enzyme action,

Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments [PDF]
, 2018 Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane sensor histidine kinase and a ...

Effects of a type-II RNA-binding protein on fatty acid composition in Synechocystis sp. PCC 6803 [PDF]
, 2010 In the cyanobacterium Synechocystis 6803, rbp3, a type-II RNA-binding protein gene, is slightly induced by temperature downshift. An rbp3 mutant shows significant reduction in total polyunsaturated fatty acids (PUFA) in membrane lipids.

The trpE Gene Negatively Regulates Differentiation of Heterocysts at the Level of Induction in Anabaena sp. Strain PCC 7120 [PDF]
, 2014 Levels of 2-oxoglutarate (2-OG) reflect nitrogen status in many bacteria. In heterocystous cyanobacteria, a spike in the 2-OG level occurs shortly after the removal of combined nitrogen from cultures and is an integral part of the induction of heterocyst
