RT   "CpeR is an activator required for expression of the phycoerythrin operon
RT   (cpeBA) in the cyanobacterium Fremyella diplosiphon and is encoded in the
RT   phycoerythrin linker-polypeptide operon (cpeCDESTR).";
RL   Mol. Microbiol. 44:1517-1531(2002).
CC   -!- FUNCTION: Covalently attaches a chromophore, probably
CC       phycoerythrobilin, to Cys residue(s) of phycobiliproteins.
CC       {ECO:0000250}.
CC   -!- INDUCTION: Induced under green light, it is part of the cpeESTR operon.
CC       {ECO:0000269|PubMed:12067341}.
CC   -!- SIMILARITY: Belongs to the CpcS/CpeS biliprotein lyase family.
CC       {ECO:0000305}.
