The present invention provides for a polyketide synthase (PKS) capable of synthesizing a 3-hydroxycarboxylic acid or ketone. The present invention also provides for a host cell comprising the PKS and when cultured produces the 3-hydroxycarboxylic acid or ketone.
biosynthesized from acyl-CoA precursors by polyketide synthases. One of the limitations to combinatorial biosynthesis of polyketides has been the lack of a toolkit that describes the means of delivering novel acyl-CoA precursors necessary for polyketide biosynthesis. Using five acid-CoA ligases obtained from various plants and microorganisms, we biosynthesized an initial library of 79 acyl-CoA thioesters by screening

Genetically modified strains of Streptomyces tsukubaensis (S. tsukubaensis) can be used for an improved fermentation process for the preparation of tacrolimus or a salt or derivative thereof by cultivation of this genetically modified strains. Novel genes allowing biosynthesis of allylmalonyl-CoA can be used for polyketide production with allylmalonyl extender unit.

The present invention relates to an FK506 derivative which has reduced immunosuppressive activity but maintains nerve regeneration activity, a preparing method thereof, and a pharmaceutical composition comprising the same for preventing or treating nervous system diseases. A composition comprising 9-deoxo-prolyl-FK506, 31-O-demethyl-FK506, or 9-deoxo-31-O-demethyl-FK506 can promote nerve regeneration and has reduced immunosuppressive activity, thereby reducing side effects in the treatment of nervous system diseases.
