    Miscellaneousi

    Miscellaneous

    The light-harvesting system in Cryptophytes contains phycobiliprotein complexes. Unusually they are composed of either phycoerythrin (CPE) or phycocyanin (CPC) but never allophycocyanin (APC), with only one type of biliprotein being present in any one species. Unlike cyanobacteria or red algae these proteins are not arranged into higher-order phycobilisome complexes, and they are found in the thylakoid lumen.
