Global Transcriptional Profiles of the Copper Responses in the Cyanobacterium Synechocystis sp. PCC 6803
Copper is an essential element involved in fundamental processes like respiration and photosynthesis. However, it becomes toxic at high concentration, which has forced organisms to control its cellular concentration. We have recently described a copper resistance system in the cyanobacterium Synechocystis sp. PCC 6803, which is mediated by the two-component system, CopRS, a RND metal transport ...
متن کاملGlobal transcriptional response of the alkali-tolerant cyanobacterium Synechocystis sp. strain PCC 6803 to a pH 10 environment.
Many cyanobacterial strains are able to grow at a pH range from neutral to pH 10 or 11. Such alkaline conditions favor cyanobacterial growth (e.g., bloom formation), and cyanobacteria must have developed strategies to adjust to changes in CO2 concentration and ion availability. Synechocystis sp. strain PCC 6803 exhibits similar photoautotrophic growth characteristics at pH 10 and pH 7.5, and we...
متن کاملFinished Genome Sequence of the Unicellular Cyanobacterium Synechocystis sp. Strain PCC 6714
Synechocystis sp. strain PCC 6714 is a unicellular cyanobacterium closely related to the popular model organism Synechocystis sp. strain PCC 6803. A combination of PacBio SMRT and Illumina GAIIx data results in a highly accurate finished genome sequence that provides a reliable resource for further comparative analyses.
متن کاملAdenylyl cyclase activity of Cya1 from the cyanobacterium Synechocystis sp. strain PCC 6803 is inhibited by bicarbonate.
Bicarbonate stimulates the activities of several class III adenylyl cyclases studied to date. However, we show here that bicarbonate decreased V(max) and substrate affinity in Cya1, a major adenylyl cyclase in the cyanobacterium Synechocystis sp. strain PCC 6803. This indicates that manifestation of the bicarbonate responsiveness is specifically modulated in Cya1.
متن کاملTranscriptional analysis and mutation of a dnaA-like gene in Synechocystis sp. strain PCC 6803.
Transcription of the dnaA gene of the cyanobacterium Synechocystis sp. strain PCC 6803 is light dependent and yields a monocistronic mRNA, as determined by Northern analysis. Surprisingly, mutants with inactivated dnaA were viable. In batch cultures under standard conditions, the mutants grew like the wild type and did not show an aberrant phenotype. We conclude that, unlike the situation in ot...
