Abstract
Disclosed are DNA sequences which are useful for the synthesis of carotenoids such as lycopene, .beta.-carotene, zeaxanthin or zeaxanthin-diglucoside, that is, DNA sequences encoding carotenoid biosynthesis enzymes. These DNA sequences are the sequences 1-6 shown in the specification. Also disclosed is a process for producing a carotenoid or a carotenoid related compound which is selected from the group consisting of geranylgeranyl pyrophosphate, phytoene, lycopene, .beta.-carotene, zeaxanthin and zeaxanthin-diglucoside, which comprises transforming a host with at least one of the DNA sequences 1-6 described above and culturing the transformant.
