4.4.1.33 | apo-[R-phycocyanin alpha-subunit] + (3E)-phycoerythrobilin |
the blue-green absorbing phycourobilin (max 495 nm) is the major phycobilin of cyanobacteria living in oceanic areas where blue light penetrates deeply into the water column |

4.4.1.33 | apo-[R-phycocyanin alpha-subunit] + (3E)-phycoerythrobilin |
the enzyme catalyses the covalent attachment of the phycobilin chromophore phycoerythrobilin to cysteine 84 of the alpha subunit of the phycobiliprotein R-phycocyanin and its isomerization to phycourobilin |

4.4.1.33 | apo-[R-phycoerythrocyanin alpha-subunit] + phycocyanobilin |
the enzyme does not use phycocyanobilin in natural conditions because no phycoviolobilin is observed in Synechococcus sp. WH8102 or any other rpcG-containing strain |
