Cluster-Level Relationships of Genes Involved in Carbon Metabolism in Synechocystis sp. PCC 6803: Development of a Novel Succinate-Producing Strain

It is found that the mutant overexpressing both rre37 and sigE produced increased levels of succinate under dark, anaerobic conditions, with a maximum productivity of 420 mg l-1.

The Multiple Functions of Common Microbial Carbon Polymers, Glycogen and PHB, during Stress Responses in the Non-Diazotrophic Cyanobacterium Synechocystis sp. PCC 6803

The very weak interrelations between the two carbon-polymer syntheses indicate that the regulation and role of PHB synthesis in Synechocystis sp.

Understanding Sugar Catabolism in Unicellular Cyanobacteria Toward the Application in Biofuel and Biomaterial Production.

This review summarizes recent studies on sugar catabolism in Synechocystis sp.

Nitrogen depletion in Arthrospira sp. PCC 8005, an ultrastructural point of view.

Inactivation of the RNA helicase CrhR impacts a specific subset of the transcriptome in the cyanobacterium Synechocystis sp. PCC 6803

The data suggest that CrhR impacts multiple aspects of RNA metabolism in Synechocystis, including the stability of strongly responding RNAs that identify examples of post-transcriptional and transcriptional regulation.

Pathway-Level Acceleration of Glycogen Catabolism by a Response Regulator in the Cyanobacterium Synechocystis Species PCC 68031[W]

Results demonstrate that Rre37 is a pathway-level regulator that activates the metabolic flow from glycogen to polyhydroxybutyrate and the hybrid tricarboxylic acid and ornithine cycle, unraveling the mechanism of the transcriptional regulation of primary metabolism in this unicellular cyanobacterium.

Positive Regulation of Sugar Catabolic Pathways in the Cyanobacterium Synechocystis sp. PCC 6803 by the Group 2 σ Factor SigE*

Results indicate that SigE functions in the transcriptional activation of sugar catabolic pathways in Synechocystis sp.

A response regulator Rre37 and an RNA polymerase sigma factor SigE represent two parallel pathways to activate sugar catabolism in a cyanobacterium Synechocystis sp. PCC 6803.

It is shown that a response regulator Rre37, whose expression is enhanced by nitrogen depletion under the control of NtcA, activates transcript accumulation of sugar catabolic genes, such as gap1, pfkA, glgP and glgX, mainly during nitrogen starvation in a cyanobacterium Synechocystis sp.

Genetic Engineering of Group 2 σ Factor SigE Widely Activates Expressions of Sugar Catabolic Genes in Synechocystis Species PCC 6803*

Overexpression of a group 2 σ factor, SigE, enhances the expressions of sugar catabolic genes in the unicellular cyanobacterium, Synechocystis sp.

Metabolomic analysis reveals rewiring of Synechocystis sp. PCC 6803 primary metabolism by ntcA overexpression.

The results demonstrate the alteration of primary metabolism by genetic engineering of NtcA, and they contribute to the current understanding of metabolic regulation of unicellular cyanobacteria.

NrrA, a nitrogen‐responsive response regulator facilitates heterocyst development in the cyanobacterium Anabaena sp. strain PCC 7120

It is concluded that the nrrA gene, which encodes a response regulator of the OmpR family with a DNA‐binding domain, facilitates heterocyst development.

Identification and characterization of two nitrogen-regulated genes of the cyanobacterium Synechococcus sp. strain PCC7942 required for maximum efficiency of nitrogen assimilation

Findings suggested that nirB is required for expression of maximum nitrite reductase activity, which seems to regulate utilization of fixed nitrogen by controlling the expression of a certain gene(s) involved in nitrogen metabolism.

Transcription of glutamine synthetase genes (glnA and glnN) from the cyanobacterium Synechocystis sp. strain PCC 6803 is differently regulated in response to nitrogen availability

It is shown that expression of both the glnA and glnN genes is subjected to transcriptional regulation in response to changes in nitrogen availability, and that an additional modification of NtcA or an additional factor is required for the regulation of glnnN gene expression.

Nitrogen availability and electron transport control the expression of glnB gene (encoding PII protein) in the cyanobacterium Synechocystis sp. PCC 6803

Primer extension analysis and band-shift assays indicated that expression of the glnB gene, elevated under nitrogen deprivation, might lie under the control of the nitrogen transcriptional regulator NtcA, although constitutive levels of expression were also detected from a σ70-dependent Escherichia coli-like promoter.
