CC   -!- FUNCTION: Covalently attaches a chromophore to Cys residue(s) of
CC       phycobiliproteins. {ECO:0000305}.
CC   -!- DISRUPTION PHENOTYPE: No visible phenotype; a triple cpcS/cpcU/cpcV
CC       deletion mutant has decreased amounts of allophycocyanin beta subunit
CC       (ApcB) compared to a double cpcS/cpcU deletion mutant. The lyase
CC       activity is therefore unsure. {ECO:0000269|PubMed:18199754}.
CC   -!- SIMILARITY: Belongs to the CpcS/CpeS biliprotein lyase family.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=ABV80288.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
