Disease relevance of Cyanophora

 

High impact information on Cyanophora

  • An ORF323 with homology to crtE, specifying prephytoene pyrophosphate dehydrogenase, is encoded by cyanelle DNA in the eukaryotic alga Cyanophora paradoxa [2].
  • A novel allophycocyanin gene (apcD) from Cyanophora paradoxa cyanelles [3].
  • To test the monophyly of glaucocystophyte cyanelles and to determine their evolutionary relationship to other plastids, complete 16S ribosomal RNA sequences were determined for Cyanophora paradoxa, Glaucocystis nostochinearum, Glaucosphaera vacuolata, and Gloeochaete wittrockiana [4].
  • In vitro synthesis of peptidoglycan precursors modified with N-acetylputrescine by Cyanophora paradoxa cyanelle envelope membranes [5].
  • The petF and rsp10 genes of the cyanellar genome of the taxonomically ambiguous flagellate Cyanophora paradoxa have been cloned, mapped, and sequenced [6].
 

Biological context of Cyanophora

 

Associations of Cyanophora with chemical compounds

  • The peptidoglycans of both species are modified with N-acetylputrescine, as has been demonstrated for cyanelle peptidoglycan of Cyanophora paradoxa [9].
  • Isolation of a novel carotenoid-rich protein in Cyanophora paradoxa that is immunologically related to the light-harvesting complexes of photosynthetic eukaryotes [10].
  • However, neither norspermidine nor norspermine was found in the taxonomically conflicting algae, Cyanophora and Glaucocystis, which contain cyanellae, or in a primitive red alga, Porphyridium [11].
  • ATP citrate lyase in the glaucocystophyte alga Cyanophora paradoxa is a cytosolic enzyme: characterisation of the gene for the large subunit at the cDNA and genomic levels [12].
  • Cycloheximide and chloroamphenicol, specific inhibitors of protein translation in the cytoplasmic and cyanellar compartments, respectively, of Cyanophora paradoxa, have been employed in 30 min pulse-labelling experiments by using [NaH-14C]O3 to label total cell proteins in vivo [13].
