Protein Variants

EC Number Protein Variants Comment Organism
1.3.99.31 additional information construction of the lycopene-producing mutant, SLYC18, and analysis of mutant strains SLYC18 and ST4, mutated in crtC and crt D or crtC genes, respectively, and quantitative analysis of their carotenoid spectrum as well as light harvesting LH1 complex, functional complementation, overview. The crtC crtD deletion mutant produces lycopene exclusively as a final product Rhodospirillum rubrum

General Information

EC Number General Information Comment Organism
1.3.99.31 metabolism CrtI produces lycopene exclusively as an end product, not as an intermediate in spirilloxanthin, carotenoid biosynthesis pathway in Rhodospirillum rubrum, overview Rhodospirillum rubrum
1.3.99.31 physiological function in vivo, lycopene is incorporated into the light-harvesting complex 1 as efficiently as the methoxylated carotenoids spirilloxanthin (in the wild-type) and 3,4,3',4'-tetrahydrospirilloxanthin (in a crtD mutant), both under semiaerobic, chemoheterotrophic, and photosynthetic, anaerobic conditions, quantitative growth experiments, overview Rhodospirillum rubrum
