Abstract

Circular dichroism spectra of thylakoid membranes and isolated chlorophyll a/b-protein complexes from Prochlorothrix hollandica and from spinach were different. The negative deflection below 650 nm was absent in Prochlorothrix. Hence, the molecular organization of the chlorophyll a/b-protein complexes of the prochlorophyte appeared strikingly different from the one in chloroplasts of higher plants and green algae. Thesedata are consistent with the relatively high chlorophyll a/b ratio in whole cells of prochlorophytes as well as in its isolated chlorophyll a/b-protein complexes.
