EC 4.4.1.31 Details
EC number
4.4.1.31
Accepted name
phycoerythrocyanin α-cysteine-84 phycoviolobilin lyase/isomerase
Reaction
[phycoerythrocyanin α-subunit]-Cys84-phycoviolobilin = apo-[phycoerythrocyanin α-subunit] + (2R,3E)-phycocyanobilin
Other name(s)
pecE (gene name), pecF (gene name), phycoviolobilin phycoerythrocyanin-α84-cystein-lyase, PecE/PecF, PEC-Cys-R84 PCB lyase/isomerase
Systematic name
[phycoerythrocyanin α-subunit]-Cys84-phycoviolobilin:(2R,3E)-phycocyanobilin lyase/isomerase
Comment
The enzyme, characterized from the cyanobacteria Nostoc sp. PCC 7120 and Mastigocladus laminosus, catalyses the covalent attachment of the phycobilin chromophore phycocyanobilin to cysteine 84 of the β subunit of the phycobiliprotein phycoerythrocyanin and its isomerization to phycoviolobilin.
