Accepted name: C-phycocyanin α-cysteine-84 phycocyanobilin lyase
Reaction: [C-phycocyanin α-subunit]-Cys84-phycocyanobilin = apo-[C-phycocyanin α-subunit] + (2R,3E)-phycocyanobilin
Glossary: phycocyanobilin = 3,31-didehydro-2,3-dihydromesobiliverdin
Other name(s): cpcE (gene name); cpcF (gene name)
Systematic name: [C-phycocyanin α-subunit]-Cys84-phycocyanobilin:(2R,3E)-phycocyanobilin lyase
Comments: The enzyme, characterized from the cyanobacterium Synechococcus elongatus PCC 7942, catalyses the covalent attachment of the phycobilin chromophore phycocyanobilin to cysteine 84 of the α subunit of the phycobiliprotein C-phycocyanin.
