General annotation (Comments)

Function

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.

Subunit structure

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.

Subcellular location

Cellular thylakoid membrane; Peripheral membrane protein; Cytoplasmic side By similarity. Note: Anchors the phycobilisome perpendicularly to the cytoplasmic surface of the thylakoid membrane By similarity.

Post-translational modification

Contains one covalently linked bilin chromophore. This protein autochromophorylates By similarity.

Sequence similarities

Belongs to the phycobilisome linker protein family.

Contains 3 PBS-linker domains.
