Protein

Chlorophyll a-b binding protein type 1 member F3, chloroplastic

Gene

CABF3

Organism
Polystichum munitum (Western swordfern) (Aspidium munitum)

Functioni

The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated.

Cofactori

Note: Binds at least 14 chlorophylls (8 Chl-a and 6 Chl-b) and carotenoids such as lutein and neoxanthin.By similarity

Family & Domainsi

Domaini

The N-terminus of the protein extends into the stroma where it is involved with adhesion of granal membranes and post-translational modifications; both are believed to mediate the distribution of excitation energy between photosystems I and II.
