Time-resolved spectroscopy of the primary photosynthetic processes of membrane-bound reaction centers from an antenna-deficient mutant of Rhodobacter capsulatus

The primary photosynthetic reactions in whole membranes of the
antenna-deficient mutant strain U43 (pTXA6–10) of Rhodobacter
capsulatus are studied by transient absorption and emission
spectroscopy with subpicosecond time resolution. Extensive
similarities between the transient absorption data on whole
membranes and on isolated reaction centers support the idea that
the primary processes in isolated reaction centers are not modified
by the isolation procedure.
