Abstract
Experiments with L-[Me-C14]methion-ine and inorganic P32 indicate that the lipids of this microorganism are metabolically stable. Lipids of unpigmented cells were incorporated into chromatophores when these cells were allowed to adapt to semi-anaerobic conditions in the light. The specific radioactivity of the phospholipid of the chromatophores was the same as that of the adapted cells; it appears that no distinction can be made between different parts of the cytoplasmic membrane system with respect to the labelling of the lipids. Chromatophores probably originate from the cytoplasmic membrane and remain structurally a part of it.This publication has 10 references indexed in Scilit:
