|
Product |
apo-[C-phycocyanin alpha-subunit];
(2R,3E)-phycocyanobilin
|
Comment |
The enzyme, characterized from the cyanobacterium Synechococcus elongatus PCC 7942, catalyses the covalent attachment of the phycobilin chromophore phycocyanobilin to cysteine 84 of the alpha subunit of the phycobiliprotein C-phycocyanin.
