Journal ArticleDOI
N and C control of ABC-type bicarbonate transporter Cmp and its LysR-type transcriptional regulator CmpR in a heterocyst-forming cyanobacterium, Anabaena sp.
TL;DR: Results show a novel mode of co-regulation by C and N availability through the concerted action of N- and C-responsive transcription factors in heterocyst-forming cyanobacteria Anabaena sp.
Journal ArticleDOI
Overexpression of SepJ alters septal morphology and heterocyst pattern regulated by diffusible signals in Anabaena
TL;DR: Results support an association between calcein transfer, SepJ‐related septal junctions, and Septal peptidoglycan nanopores in the model organism Anabaena, and support a role of SepJ in the intercellular transfer of regulatory signals for heterocyst differentiation.
Book ChapterDOI
Cyanobacterial Nitrogen Assimilation Genes and NtcA-Dependent Control of Gene Expression
TL;DR: Current knowledge, at the genetic level, of the pathways of assimilation of ammonium, nitrate (and nitrite) and dinitrogen in the cyanobacteria are summarized and what is known about the molecular mechanism underlying repression by ammonium in these organisms is described.
Journal ArticleDOI
The nuiA gene from Anabaena sp. encoding an inhibitor of the NucA sugar-non-specific nuclease.
TL;DR: An open reading frame composed of 135 codons is named nuiA, whose expression in E. coli conferred heat-resistant NucA-inhibitory activity to cell-free extracts, and represents a novel gene encoding a nuclease inhibitor.
Journal ArticleDOI
FtsZ of Filamentous, Heterocyst-Forming Cyanobacteria Has a Conserved N-Terminal Peptide Required for Normal FtsZ Polymerization and Cell Division
Laura Corrales-Guerrero,Sergio Camargo,Ana Valladares,Silvia Picossi,Ignacio Luque,Jesús A. G. Ochoa de Alda,Antonia Herrero +6 more
TL;DR: The N-terminal FTSZ sequence appears to contribute to a distinct FtsZ polymerization mode that is essential for cell division and division plane location in Anabaena.
