| Research Abstract |
In the present study, the biosynthetic pathway for the anti -tubercular agent, D-cycloserine (DCS), was elucidated by the gene disruption analysis of the DCS biosynthetic gene cluster in a DCS-producing Streptomyces lavendulae ATCC11924. In addition, DCS production system in Escherichia (E.) coli was established by introducing the DCS biosynthetic genes into E. coli. Furthermore, DcsA was found to be a novel heme protein involved in the biosynthesis of DCS.
