DE   C-phycoerythrin beta-cysteine-48/59 phycoerythrobilin lyase.
CA   phycoerythrobilin-L-cysteinyl(48)/L-cysteinyl(59)-[C-phycoerythrin beta-
CA   subunit] = (2R,3E)-phycoerythrobilin + apo-L-
CA   cysteinyl(48)/L-cysteinyl(59)-[C-phycoerythrin beta-subunit].
CC   -!- The enzyme, characterized from the cyanobacterium Microchaete
CC       diplosiphon, catalyzes the attachment of the phycobilin chromophore
CC       (3E)-phycoerythrobilin (PEB) to cysteine 48 and 59 of the beta
CC       subunits of the phycobiliprotein C-phycoerythrin.
CC   -!- The enzyme first ligates the A ring of PEB to cysteine-48, followed
CC       by the attachment of the D ring to cysteine-59.
CC   -!- The numbering used here corresponds to the enzyme from Microchaete
CC       diplosiphon, and could vary slightly in other organisms.
CC   -!- The reaction requires the presence of the chaperone-like protein
CC       CpeZ.
