Characterization of tylM3/tylM2 and mydC/mycB pairs required for efficient glycosyltransfer in macrolide antibiotic biosynthesis.
Melancon C.E. III, Takahashi H., Liu H.W.
The heterologous expression of tylM3 and mydC, two homologous genes of previously unknown function, along with genes encoding their respective partner glycosyltransferases, tylM2 and mycB, and the necessary sugar biosynthesis genes significantly enhances the glycosyltransferase activity in the eng ... >> More
The heterologous expression of tylM3 and mydC, two homologous genes of previously unknown function, along with genes encoding their respective partner glycosyltransferases, tylM2 and mycB, and the necessary sugar biosynthesis genes significantly enhances the glycosyltransferase activity in the engineered Streptomyces venezuelae host in which the native glycosyltransferase, desVII, has been inactivated. Both glycosyltransferases accept the endogenous 12-membered macrolide, 10-deoxymethynolide, or the exogenously fed 16-membered macrolide, tylactone. Five new compounds were generated using this expression system. This work suggests that the 13 other known TylM3/MydC/DesVIII homologues found in macrolide and anthracycline antibiotic clusters likely function as glycosyltransferase auxiliary proteins as well. These findings will greatly assist endeavors to generate new natural products in these pathways in a combinatorial fashion. << Less

Analysis of four tylosin biosynthetic genes from the tylLM region of Streptomyces fradiae.
Gandecha A.R., Large S.L., Cundliffe E.
The tylLM region of the tylosin biosynthetic gene cluster of Streptomyces fradiae contains four open reading frames (orfs1*-4*). The function of the orf1* product is not known. The product of orf2* (tylM2) is the glycosyltransferase that adds mycaminose to the 5-hydroxyl group of tylactone, the po ... >> More
The tylLM region of the tylosin biosynthetic gene cluster of Streptomyces fradiae contains four open reading frames (orfs1*-4*). The function of the orf1* product is not known. The product of orf2* (tylM2) is the glycosyltransferase that adds mycaminose to the 5-hydroxyl group of tylactone, the polyketide aglycone of tylosin (Ty). A methyltransferase, responsible for 3-N-methylation during mycaminose production, is encoded by orf3* (tylM1). The product of orf4* (cer) is crotonyl-CoA reductase, which converts acetoacetyl-CoA to butyryl-CoA for use as a 4C extender unit during tylactone production. << Less
