ENZYME entry: EC 4.4.1.33
| Accepted Name |
|---|
| R-phycocyanin alpha-cysteine-84 phycourobilin lyase/isomerase.
|
| Reaction catalysed |
|---|
| phycourobilin-L-cysteinyl(84)-[R-phycocyanin alpha-subunit] <=> (2R,3E)-phycoerythrobilin + apo-L-cysteinyl(84)-[R-phycocyanin alpha-subunit] |
| 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.
