Protein Domain : IPR000066

Type:  Domain Name:  Antenna complex, alpha/beta subunit
Description:  The antenna complexes of photosynthetic bacteria function as light-harvesting systems that absorb light and transfer the excitation energy to the reaction centres. The antenna complexes usually comprise 2polypeptides (alpha- and beta-chains), 2-3 bacteriochlorophyll molecules and some carotenoids [, ].The alpha- and beta-chains are small proteins of 40-70 residues. Each has an N-terminal hydrophilic cytoplasmic domain, a single transmembrane (TM)region, and a small C-terminal hydrophilic periplasmic domain. In both chains, the TM domain houses a conserved His residue, presumed to beinvolved in binding the magnesium atom of a bacteriochlorophyll group. The beta-chains are characterised by a further histidine at the C-terminalextremity of the cytoplasmic domain, which is also thought to be involved in bacteriochlorophyll binding. Short Name:  Antenna_a/b
