Disease relevance of Phycourobilin


High impact information on Phycourobilin

  • (Formula: see text) The bilins in all these peptides are attached through single linkages to a cysteinyl residue, except for the phycourobilin on peptide beta-3 which is attached through two thioether linkages to cysteinyl residues 10 amino acids apart [4].
  • Structure and apoprotein linkages of phycourobilin [5].
  • ITS-based phylogenies partitioned marine cluster A Synechococcus into six clades, three of which can be associated with a particular phenotype (motility, chromatic adaptation, and lack of phycourobilin) [6].
