摘要
Large molecular aggregates, condensed biological macromolecules, intact membrane systems, and cell organelles often exhibit intense anomalous circular dichroism (CD) bands which are absent in systems of lower structural complexity. Theory predicts that in dense, chirally organized macroaggregates the size of the aggregate controls the magnitude of the anomalous CD bands [Keller, D., & Bustamante, C. (1986) J. Chem. Phys. 84, 2972-2979]. Photosynthetic pigment-protein complexes in their native thylakoid membranes and in vitro were used to provide direct experimental evidence of the size dependency of CD in macroaggregates.
