ENZYME entry: EC 4.4.1.31

Accepted Name
Phycoerythrocyanin alpha-cysteine-84 phycoviolobilin lyase/isomerase.
Alternative Name(s)
Phycoviolobilin phycoerythrocyanin-alpha-84-cystein-lyase.
Reaction catalysed
[Phycoerythrocyanin alpha-subunit]-Cys(84)-phycoviolobilin <=> apo-[phycoerythrocyanin alpha-subunit] + (2R,3E)-phycocyanobilin
Comment(s)
The enzyme, characterized from the cyanobacteria Nostoc sp. PCC 7120 and Mastigocladus laminosus, catalyzes the covalent attachment of the phycobilin chromophore phycocyanobilin to cysteine 84 of the beta subunit of the phycobiliprotein phycoerythrocyanin and its isomerization to phycoviolobilin.
