Bipolar localization of putative photoreceptor protein for phototaxis in thermophilic cyanobacterium Synechococcus elongatus.

چکیده
We identified an open reading frame from a database of the entire genome of Synechococcus elongatus, the product of which was very similar to pixJ1, which was proposed as photoreceptor gene for phototaxis in Synechocystis sp. PCC6803 [Yoshihara et al. (2000) Plant Cell Physiol. 41: 1299]. The mRNA of S. elongatus pixJ (SepixJ) was expressed in vivo as a part of the product of an operon. SePixJ was detected exclusively in the membrane fraction after cell fractionation. Immunogold labeling of SePixJ in ultra-thin sections indicated that it existed only in both ends of the rod-shaped cell; probably bound with the cytoplasmic membrane.

Complete sequence of one copy of the psbA gene from the thermophilic cyanobacterium Synechococcus elongatus.
One copy of the psbA gene which codes for the photosystem II reaction center D-1 protein from the thermophilic cyanobacterium Synechococcus elongatus has been sequenced. It is feasible that a disulfide bridge between D-1 Cys212 and D-2 Cys212 is responsible for the thermostability of the photosystem II reaction center from Synechococcus elongatus.
متن کاملSequence of the two operons encoding the four core subunits of the cytochrome b(6)f complex from the thermophilic Cyanobacterium synechococcus elongatus.
The genes encoding cytochrome f (petA), cytochrome b(6) (petB), the Rieske FeS-protein (petC), and subunit IV (petD) of the cytochrome b(6)f complex from the thermophilic cyanobacterium Synechococcus elongatus were cloned and sequenced. Similar to other cyanobacteria, the structural genes are arranged in two short, single-copy operons, petC/petA and petB/petD, respectively. In addition, five op...
متن کاملEffect of salinity on some physiological and biochemical responses in the cyanobacterium Synechococcus elongatus
In this study, some physiological and biochemical responses of Synechococcus elongatus to salt stress were investigated. The cyanobactrium was grown in BG-11 medium under different concentrations of NaCl (0, 0.5, 1 M). The results indicated that the growth of S. elongatus was significantly inhibited under salt stress on days 5, 9 and 12. Protein content increased in S. elongatus on day 12 in pr...
متن کاملComparative analysis to identify determinants of changing life style in Thermosynechococcus elongatus BP-1, a thermophilic cyanobacterium.
A comparative genomics analysis among all forty whole genome sequences available for cyanobacteria (3 thermophiles- Thermosynechococcus elongatus BP-1, Synechococcus sp. JA-2-3B'a (2-13), Synechococcus sp. JA-3-3Ab and 37 mesophiles) was performed to identify genomic and proteomic factors responsible for the behaviour of T. elongatus BP-1, a thermophilic unicellular cyanobacterium with optimum ...
متن کاملTargeted disruption of psbX and biochemical characterization of photosystem II complex in the thermophilic cyanobacterium Synechococcus elongatus.
PSII-X is a small hydrophobic protein, which is universally present in photosystem II (PSII) core complex among cyanobacteria and plants. The role of PSII-X was studied by directed mutagenesis and biochemical analysis in the thermophilic cyanobacterium Synechococcus elongatus. The psbX-disrupted mutant could grow photoautotrophically indicative of non-essential function, while it showed growth ...
