-'''Phycoerythrobilin''' is a red [[phycobilin]], i.e. an open [[tetrapyrrole]] [[chromophore]] found in [[cyanobacteria]] and in the [[chloroplast]]s of [[red algae]], [[glaucophyte]]s and some [[cryptomonad]]s. Phycoerythrobilin is present in the [[phycobiliprotein]] [[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 the [[phycocyanin]], then termed R-Phycocyanin. Like all phycobilins, phycoerythrobilin is covalently linked to these phycobiliproteins by a thioether bond.
