定義
bacteriorhodopsin: A membraneboundprotein of the halophilic (saltresistant)bacterium Halobacteriumhalobium. When activated by light, itpumps protons out of the cell; thiscreates a concentration gradient,which enables ATP to be synthesized.Bacteriorhodopsin is composed ofseven α-helix segments, which spanthe membrane and are joined togetherby short amino-acid chains. Itcontains the prosthetic group retinal,which is also found in the pigmentrhodopsin in the rod cells of vertebrates.
一般的な説明
Bacteriorhodopsin (BR) is a covalent complex comprising bacterioopsin protein and retinal cofactor in the equimolar ratio. It corresponds to the molecular weight of 27kDa. BR belongs to the retinylidene class of proteins. It is a seven-membrane helical protein that acts as a photon-driven pump. BR can be used in studies of the folding and kenetics of β-helical proteins.
