Comments There are a number of different subfamilies; some act as heterodimers, others not and they attach different chromophores to different apo-biliproteins depending on the organsism. We have not attempted to define them separately. See: PubMed=18199754; DOI=10.1074/jbc.M708164200; Shen G., Schluchter W.M., Bryant D.A.; "Biogenesis of phycobiliproteins: I. cpcS-I and cpcU mutants of the cyanobacterium Synechococcus sp. PCC 7002 define a heterodimeric phyococyanobilin lyase specific for beta-phycocyanin and allophycocyanin subunits."; J. Biol. Chem. 283:7503-7512(2008).
