IntEnz Enzyme Nomenclature


Accepted name:
tylactone mycaminosyltransferase
Other name:
tylM2 (gene name)
Systematic name:
dTDP-α-D-mycaminose:tylactone 5-O-β-D-mycaminosyltransferase



The enzyme participates in the biosynthetic pathway of the macrolide antibiotic tylosin, which is produced by several species of Streptomyces bacteria. Activity is significantly enhanced by the presence of an accessory protein encoded by the tylM3 gene.
