Comments The enzyme, characterized from the cyanobacteria?Nostoc?sp. PCC 7120 and?Mastigocladus laminosus, catalyses the covalent attachment of the phycobilin chromophore phycocyanobilin to cysteine 84 of the ¦Â subunit of the phycobiliprotein phycoerythrocyanin and its isomerization to phycoviolobilin.
Cofactor
History
Reactions [Phycoerythrocyanin alpha-subunit]-Cys(84)-phycoviolobilin = apo- [phycoerythrocyanin alpha-subunit] + (2R,3E)-phycocyanobilin.
