Accumulation of Polyene Precursors of Neurosporene in Mutant Strains of Rhodopseudomonas spheroides

Nature volume 198, pages 1227–1228 (1963)Cite this article

Abstract

JENSEN et al. have proposed that the biosynthesis of carotenoid pigments in the photosynthetic bacterium Rhodopseudomonas spheroides proceeds by the following sequence of reactions1,2: Mutant strains have been known for several years which do not form spheroidene or spheroidenone but accumulate precursors in the biosynthetic pathway. One of these mutants, strain Ga, accumulates neurosporene and chloroxanthin (hydroxyneurosporene)3; a second, strain uv-33, accumulates phytoene4.
