Autoignition=Phycoerythrobilin is a red
phycobilin , i.e. an opentetrapyrrole chromophore found incyanobacteria and in thechloroplast s ofred algae ,glaucophyte s and somecryptomonad s. Phycoerythrobilin is present in thephycobiliprotein phycoerythrin , of which it is the terminal acceptor of energy. The amount of phycoerythrobilin in phycoerythrins varies a lot, depending on the considered organism. In some Rhodophytes and oceanic cyanobacteria, phycoerythrobilin is also present in thephycocyanin , then termed R-Phycocyanin. Like all phycobilins, phycoerythrobilin is covalently linked to these phycobiliproteins by a thioether bond.External links
