Sysname
[phycoerythrocyanin alpha-subunit]-Cys84-phycoviolobilin:(2R,3E)-phycocyanobilin lyase/isomerase
Reaction(IUBMB)
[phycoerythrocyanin alpha-subunit]-Cys84-phycoviolobilin = apo-[phycoerythrocyanin alpha-subunit] + (2R,3E)-phycocyanobilin
Substrate
[phycoerythrocyanin alpha-subunit]-Cys84-phycoviolobilin
Product
apo-[phycoerythrocyanin alpha-subunit];
(2R,3E)-phycocyanobilin
Comment
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 beta subunit of the phycobiliprotein phycoerythrocyanin and its isomerization to phycoviolobilin.
