General annotation (Comments)

Function

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

Cofactor

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

Subunit structure

The LHC complex consists of chlorophyll a-b binding proteins. Interacts (via T14 domain) with LTD. Interacts with CAO/cpSRP43 during its post-translational targeting to the thylakoid. Ref.7 Ref.8

Subcellular location

Plastid › chloroplast thylakoid membrane; Multi-pass membrane protein.

Domain

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.

The L18 domain (188-205) is required for the transit complex formation with CAO/cpSRP43 and the targeting to the thylakoid.

The T14 domain (211-224) is required for the interaction with LTD and the translocation across the envelope.

Post-translational modification

Photoregulated by reversible phosphorylation of its threonine residues By similarity.

Sequence similarities

Belongs to the light-harvesting chlorophyll a/b-binding (LHC) protein family.
