(57) [Summary] [Structure] A DNA chain comprising a base sequence encoding a polypeptide having the amino acid sequence shown in SEQ ID NO: 1 or SEQ ID NO: 2, which has the property of increasing the production amount of carotenoid. Alternatively, a method for producing carotenoid, which comprises introducing a DNA chain that hybridizes with it, and introducing the DNA chain into a carotenoid-producing microorganism and culturing the transformed microorganism in a medium to increase the carotenoid content of the culture. [Effects] According to the present invention, the production amount of carotenoid can be significantly increased in biosynthesis of carotenoids by microorganisms. |
