UniProt functional annotation for Q3J1A3

UniProt code: Q3J1A3.

Organism: Rhodobacter sphaeroides (strain ATCC 17023 / DSM 158 / JCM 6121 / NBRC 12203 / NCIMB 8253 / ATH 2.4.1.) (Cereibacter sphaeroides).
Taxonomy: Bacteria; Proteobacteria; Alphaproteobacteria; Rhodobacterales; Rhodobacteraceae; Luteovulum.
 
Function: Antenna complexes are light-harvesting systems, which transfer the excitation energy to the reaction centers.
 
Subunit: 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.
Similarity: Belongs to the antenna complex beta subunit family. {ECO:0000305}.
