Abstract：
:The time dependent assembly of the photosynthetic apparatus was studied in Rhodospirillum rubrum after transfer of cells growing aerobically in the dark to low aeration. While bacteriochlorophyll (Bchl) cellular levels increase continuously levels of soluble cytochrome C2 do not change significantly. Absorption spectra of membranes isolated at different times after transfer reveal that incorporation of carotenoids lags behind incorporation of Bchl. However, a carotenoid fraction exhibiting spectral properties of spirilloxanthin isomers was isolated apart from membranes. This carotenoid fraction even was present in homogenates from Bchl-free, aerobically grown cells. Incorporation of U-14C-proteinhydrolyzate into membrane proteins showed that proteins are mainly formed which are specific for photosynthetic membranes. Although the proportion of reaction center (RC) Bchl per light harvesting (LH) Bchl does not change the proportions of membrane proteins present in RC and LH preparations change initially. But later on the proportions of the different proteins also reach constant values. Concerning proteins characteristic for cytoplasmic membranes a differential incorporation of label can be observed. The data indicate that the photosynthetic apparatus in Rhodospirillum rubrum is assembled through a sequential mechanism.
