Nucleotide sequence of the psaC gene of the cyanobacterium Synechococcus vulcanus.

Cloning, characterization, and transcriptional analysis of a gene encoding an alpha-crystallin-related, small heat shock protein from the thermophilic cyanobacterium Synechococcus vulcanus.

hspA, a gene encoding a 16-kDa heat-induced protein from the thermophilic cyanobacterium Synechococcus vulcanus, has been cloned and sequenced. The deduced amino acid sequence of the gene product showed significant homology to sequences of the family of alpha-crystallin-related, small heat shock proteins. A monocistronic mRNA of hspA increased transiently in response to heat shock. The heat sho...

Nucleotide sequence of plasmid pAQ1 of marine cyanobacterium Synechococcus sp. PCC7002.

We have determined the complete nucleotide sequence of pAQ1, the smallest plasmid of the unicellular marine cyanobacterium Synechococcus sp. PCC7002. The plasmid consists of 4,809 bp and has at least four open reading frames that potentially encode polypeptides of 50 or more amino acids. We found that a palindromic element, the core sequence of which is G(G/A)CGATCGCC, is over-represented not o...

Nucleotide sequence of the psaE gene of cyanobacterium Synechococcus sp. PCC 6301.

The cyanobacterial PSI complex is a membrane-bound, photooxidoreductase that catalyzes the light-driven transport of electrons from reduced plastocyanin (or Cyt cSs3) to oxidized, soluble Fd or flavodoxin (for a review, see Golbeck and Bryant, 1991). The complex probably comprises single copies of 11 or 12 different polypeptides, about 100 Chl a molecules, 10 to 15 p-carotene molecules, 2 molec...

Cloning, Characterization, and Transcriptional Analysis of a Gene Encoding an a-Crystallin-Related, Small Heat Shock Protein from the Thermophilic Cyanobacterium Synechococcus vulcanus

A novel plasmid recombination mechanism of the marine cyanobacterium Synechococcus sp. PCC7002.

We describe a novel mechanism of site-specific recombination in the unicellular marine cyanobacterium Synechococcus sp. PCC7002. The specific recombination sites on the smallest plasmid pAQ1 were localized by studying the properties of pAQ1-derived shuttle-vectors. We found that a palindromic element, the core sequence of which is G(G/A)CGATCGCC, functions as a resolution site for site-specific...
