| Research Abstract |
A transcriptional regulator LitR of Thermus thermophilus HB8 acts as an repressor which binds to upstream region of carotenoid biosynthesis genes and releases repression depending blue light. This regulatory system was used for constructing a light-dependent gene expression system. A DNA fragment containing the litR gene and LitR-binding region was inserted into an expression vector containing a reporter gene in E. coli and T. thermophilus. The results of gene expression response to blue light irradiation suggested the feasibility of the light-dependent gene expression system using LitR.
