phycoérytrine
Phycoerythrine is a red photosynthetic pigment found in cyanobacteria, red algae, and some dinoflagellates. It is a member of the phycobiliprotein family, which are protein complexes that absorb light energy and transfer it to chlorophyll during photosynthesis. Phycoerythrine has a distinct red fluorescence, making it useful in various biological and medical applications.
The structure of phycoerythrine consists of a protein backbone to which light-absorbing chromophores, called phycoerythrobilins, are
Due to its strong fluorescence and relatively small size, purified phycoerythrine is widely used as a fluorescent
