Vectors and plasmids including such DNA, are also set forth. The invention also includes host cells transformed by such DNAs, or vectors or plasmids containing such DNAs. A process for the production of isoprenoids and carotenoids using such transformed host cells is also provided.Type: GrantFiled: May 6, 1999Date of Patent: September 4, 2001Assignee: Roche Vitamins Inc.Inventors: Tatsuo Hoshino, Kazuyuki Ojima, Yutaka Setoguchi
