ENZYME entry: EC 4.4.1.33

Accepted Name
R-phycocyanin alpha-cysteine-84 phycourobilin lyase/isomerase.
Reaction catalysed
[R-phycocyanin alpha-subunit]-Cys(84)-phycourobilin <=> apo-[R-phycocyanin alpha-subunit] + (2R,3E)-phycoerythrobilin
Comment(s)
The enzyme, characterized from the cyanobacterium Synechococcus sp. WH8102, catalyzes the covalent attachment of the phycobilin chromophore phycoerythrobilin to cysteine 84 of the alpha subunit of the phycobiliprotein R-phycocyanin and its isomerization to phycourobilin.
