Disease relevance of Phycourobilin

The latter is similar to phycoerythrins (PE) from marine Synechococcus cyanobacteria and bind a phycourobilin-like pigment as the major chromophore [1].
Phycoerythrins of marine unicellular cyanobacteria. II. Characterization of phycobiliproteins with unusually high phycourobilin content [2].
A survey of marine unicellular cyanobacterial strains for phycobiliproteins with high phycourobilin (PUB) content led to a detailed investigation of Synechocystis sp. WH8501 [2].
Phycourobilin is the major chromophore in low-light-adapted Prochlorococcus ecotypes such as strain SS120 [3].

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].

Associations of Phycourobilin with other chemical compounds

This monomeric enzyme catalyzes binding of the green-absorbing phycoerythrobilin at cysteine 84 with concomitant isomerization to phycourobilin [7].
