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. | |
