DE   phycoerythrocyanin alpha-cysteine-84 phycoviolobilin lyase/isomerase.
AN   phycoviolobilin phycoerythrocyanin-alpha84-cystein-lyase.
CA   phycoviolobilin-L-cysteinyl(84)-[phycoerythrocyanin alpha-subunit] =
CA   (2R,3E)-phycocyanobilin + apo-L-cysteinyl(84)-[phycoerythrocyanin alpha-
CA   subunit].
CC   -!- The enzyme, characterized from the cyanobacteria Nostoc sp. PCC 7120
CC       and Mastigocladus laminosus, catalyzes the covalent attachment of the
CC       phycobilin chromophore phycocyanobilin to cysteine 84 of the beta
CC       subunit of the phycobiliprotein phycoerythrocyanin and its
CC       isomerization to phycoviolobilin.
