INTEGRAL MEMBRANE PERIPHERAL LIGHT HARVESTING COMPLEX FROM RHODOPSEUDOMONAS ACIDOPHILA STRAIN 10050
Overview
The refined structure of the peripheral light-harvesting complex from, Rhodopseudomonas acidophila strain 10050 reveals a membrane protein with, protein-protein interactions in the trans-membrane region exclusively of a, van der Waals nature. The dominant factors in the formation of the complex, appear to be extramembranous hydrogen bonds (suggesting that each, apoprotein must achieve a fold close to its final structure in order to, oligomerize), protein-pigment and pigment-pigment interactions within the, membrane-spanning region. The pigment molecules are known to play an, important role in the formation of bacterial light-harvesters, and their, extensive mediation of structural contacts within the membrane bears this, out. Amino acid residues determining the secondary structure of the, ... [(full description)]
