Disease relevance of Porphyra

  • The deduced polypeptide sequence is homologous to other reported HOs from organisms containing phycobilisomes (Porphyra purpurea and Synechocystis sp. strain PCC 6803) and, to a lesser extent, to vertebrate enzymes [1].

High impact information on Porphyra

  • This fraction could be replaced with commercial ferredoxin derived from spinach or the red alga, Porphyra umbilicalis [2].
  • Variant forms of a group I intron in nuclear small-subunit rRNA genes of the marine red alga Porphyra spiralis var. amplifolia [3].
  • The cp-genome of C. caldarium cannot be readily aligned with that of Porphyra purpurea, a multicellular red alga, or Guillardia theta due to a displacement of a region of the cp-genome [4].
  • We previously reported that fatty acyl-CoA esters activate ryanodine receptor/Ca2+ release channels in a terminal cisternae fraction from rabbit skeletal muscle [Fulceri, Nori, Gamberucci, Volpe, Giunti and Benedetti (1994) Cell Calcium 15, 109-116] [5].
  • The 5S ribosomal RNA sequences have been determined for the rhodoplast of the red alga Porphyra umbilicalis and the chloroplast of the conifer Juniperus media [6].

Biological context of Porphyra


Associations of Porphyra with chemical compounds

  • An earlier report (T. Fujiwara, J. Biochem. 49:361-367, 1961) contended, on the basis of the isolation of sugar-containing peptic chromopeptides from Porphyra tenera R-phycoerythrin, that this red algal phycobiliprotein is a glycoprotein [12].
  • To investigate the role of the heme axial ligand in the conformational stability of c-type cytochrome, we constructed M58C and M58H mutants of the red alga Porphyra yezoensis cytochrome c(6) in which the sixth heme iron ligand (Met58) was replaced with Cys and His residues, respectively [13].
  • ESI-MS/MS showed unusual small radical losses, generally resulting from the loss of a methyl group with the exception of shinorine and porphyra for which the initial losses were 30 and 44 Da, respectively [14].
  • Polysaccharide from Porphyra yezoensis (PYPS) was degraded by ultrasound in this study [15].
  • Three porphyran preparations with high emulsifying ability and varying molecular mass, 3,6-anhydrogalactose content, and sulfate content without any protenaceous component were prepared from dried nori processed from Porphyra yezoensis, a red alga [16].
