Protein

Phycobiliprotein ApcE

Gene

apcE

Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

This protein is postulated to act both as terminal energy acceptor (by its phycobilin-like domains) and as a linker polypeptide (by its repeats and arms) that stabilizes the phycobilisome core architecture. Has intrinsic bilin lyase activity (By similarity).By similarity

Interactioni

Subunit structurei

Heterodimer of ApcF (a variant beta-allophycocyanin). Phycobilisomes of this organism are composed of a two cylinder core, from which six rods radiate. The core is mainly composed of allophycocyanin alpha and beta chains and of minor components (By similarity).By similarity
