Abstract
SUMMARY: The magnitude of self-shading in light-grown cultures of Rhodopseudomonas spheroides has been estimated. When a culture of R. spheroides is transferred from bright light to dim light there is preferential synthesis of bacteriochlorophyll and carotenoid pigments relative to net protein synthesis. Protein turnover does not account for this.
