---|---|---|
malfunction | a mutant of Rubrivivax gelatinosus lacking the crtI gene produces only phytoene, indicating that this organism has no other phytoene desaturases. When the crtI deletion mutant is complemented by the three-step phytoene desaturase of Rhodobacter capsulatus, spirilloxanthin and its precursors are not synthesized, although spheroidene and OH-spheroidene are accumulated | Rubrivivax gelatinosus |
physiological function | the enzyme simultaneously catalyzes a three- and four-step desaturation of phytoene producing both neurosporene and lycopene | Rubrivivax gelatinosus |
