摘要:Macrolides particularly erythromycins and azithromycins, having O-mycaminosyl or O-angolosaminyl groups, particularly at the 5 -position, are produced using a gene cassette comprising a combination of genes which, in an appropriate strain background, are able to direct the synthesis of mycaminose or angolosamine and to direct its subsequent transfer to an aglycone or pseudoaglycone. Synthetic genes may comprise one or more of angMIII, angMI, angB, angAI, angAII, angorf14, angorf4, tylMIII, tylMI, tylB, tylAI, tylAII, eryCVI, spnO, eryBVI, eryK, tyl Ia and ery G. Glycosyltransfer genes may comprise one or more of eryCIII, tylMII, angMII, desVII, eryBV, spnP and midI.

标题 :Biosynthesis of polyketide synthase substrates
发明人：KHOSLA CHAITAN; PFEIFER BLAINE
摘要:The use of enzymes which catalyze the production of starter and extender units for polyketides is described. In addition, modified loading modules are described, which can accept a variety of starting units such as substituted benzoates, and which can be used to generate substituted derivatives of natural products. These enzymes may be used to enhance the yield of polyketides that are natively produced or polyketides that are rationally designed. By using these techniques, the synthesis of a complete polyketide has been achieved in E. coli . Production can be enhanced in microbial organisms of polyketides and other secondary metabolites by delaying production until after exponential phase and by maintaining relatively constant nutrient levels in the medium. In addition, polyketide production can be enhanced by providing an expression system for a thioesterase II. Thus, by modifying the host organism and changing the culture conditions, synthesis of a secondary metabolite can be enhanced. The present invention also results in a host organism with desirable characteristics to be used in the production of such polyketides and to assess the results of gene shuffling.

标题:Metabolic engineering of polyhydroxyalkanoate monomer synthases
发明人：SHERMAN DAVID H; WILLIAMS MARK D; XUE YONGQUAN
权利人:UNIV MINNESOTA
摘要:A novel pathway for the synthesis of polyhydroxyalkanoate is provided. A method of synthesizing a recombinant polyhydroxyalkanoate monomer synthase is also provided. These recombinant polyhydroxyalknoate synthases are derived from multifunctional fatty acid synthases or polyketide synthases and generate hydroxyacyl acids capable of polymerization by a polyhydroxyalknoate synthase.
