Calcium impacts carbon and nitrogen balance in the filamentous cyanobacterium Anabaena sp. PCC 7120
Calcium is integral to the perception, communication and adjustment of cellular responses to environmental changes. However, the role of Ca(2+) in fine-tuning cellular responses of wild-type cyanobacteria under favourable growth conditions has not been examined. In this study, extracellular Ca(2+) has been altered, and changes in the whole transcriptome of Anabaena sp. PCC 7120 have been evalua...
متن کاملCell Surface-Associated Proteins in the Filamentous Cyanobacterium Anabaena sp. strain PCC 7120
The cell surface senses environmental changes first and transfers signals into the cell. To understand the response to environmental changes, it is necessary to analyze cell surface components, particularly cell surface-associated proteins. We therefore investigated cell surface-associated proteins from the filamentous cyanobacterium Anabaena sp. strain PCC 7120. The cell surface-associated pro...
متن کاملStrong and regulated promoters in the cyanobacterium Anabaena PCC 7120.
The strengths of several promoters were assessed in the cyanobacterium Anabaena PCC 7120 by fusing them to luxAB, encoding bacterial luciferase. Two promoters, Ptac and PpsbA, with sequences nearly identical to consensus Escherichia coli sigma 70 promoters, gave as high or higher expression than the strong Anabaena promoter, Prbc. Pnpt, the natural promoter driving expression of the kanamycin-r...
متن کاملAn amidase is required for proper intercellular communication in the filamentous cyanobacterium Anabaena sp. PCC 7120.
Channels that cross cell walls and connect the cytoplasm of neighboring cells in multicellular cyanobacteria are pivotal for intercellular communication. We find that the product of the gene all1140 of the filamentous cyanobacterium Anabaena sp. PCC 7120 is required for proper channel formation. All1140 encodes an amidase that hydrolyses purified peptidoglycans. An All1140-GFP fusion protein is...
متن کاملComplete genomic sequence of the filamentous nitrogen-fixing cyanobacterium Anabaena sp. strain PCC 7120.
The nucleotide sequence of the entire genome of a filamentous cyanobacterium, Anabaena sp. strain PCC 7120, was determined. The genome of Anabaena consisted of a single chromosome (6,413,771 bp) and six plasmids, designated pCC7120alpha (408,101 bp), pCC7120beta (186,614 bp), pCC7120gamma (101,965 bp), pCC7120delta (55,414 bp), pCC7120epsilon (40,340 bp), and pCC7120zeta (5,584 bp). The chromos...
