General annotation (Comments)

Function

Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.

Subunit structure

The core complex is formed by different alpha and beta chains, binding bacteriochlorophyll molecules, and arranged most probably in tetrameric structures disposed around the reaction center. The non-pigmented gamma chains may constitute additional components.

Subcellular location

Cell inner membrane; Single-pass type II membrane protein.

Sequence similarities

Belongs to the antena complex beta subunit family.
