    • The invention provides a novel technology for glycosylation of natural products using novel genetically engineered strains of bacteria. These in vivo glycosylation systems of the invention express a heterologous glycosyltransferase and deoxysugar pathway that are capable of glycosylating a suitable substrate, which can be added to a culture broth. The invention also provides novel compounds glycosylated by these novel genetically engineered strains (the in vivo glycosylation systems of the invention), including novel peptides, mixed polyketide-peptides, or polyketides, including novel macrolides, e.g., glycosylated spinosyn derivatives, glycosylated derivatives of antibiotics such as erythromycin, tetracycline, rifampicin, glycosylated derivatives of anti-tumor drugs such as daunorubicin, mithramycin, derivatives of immunosuppressants such as rapamycin, FK520, FK506, glycosylated derivatives of anti-fungals such as amphotericin, glycosylated derivatives of antibacterials such as tylosin, glycosylated derivatives of antiparasitics such as avermectin, glycosylated derivatives of insecticides such as spinosyn, and methods for making these compounds using the in vivoglycosylation systems of the invention.
