Studies of photosynthetic energy conversion
Spectroscopic studies are reported on the major pigmented components of bacterial photosynthetic membranes: antenna complexes and photochemical reaction centers of Rhodopseudomonas sphaeroides and related species. Through optical studies with polarized light, combining the techniques of linear dichroism and photoselection, the relative orientations have been determined of pigment molecules in reaction centers and antenna complexes and in relation to the photosynthetic membrane. Fairly complete angular coordinates have been obtained of bacterio-chlorophyll (bchl) and bacteriopheophytin in the reaction centers, and less detailed information about antenna pigments (bchl and carotenoids) and bound cytochromes. The result of this kind of work in several laboratories has been a more specific view of the molecular geometry of the reaction center, as related to its photochemical function.
