EC 2.4.1.316     
Accepted name: tylactone mycaminosyltransferase
Reaction: tylactone + dTDP-α-D-mycaminose = dTDP + 5-O-β-D-mycaminosyltylactone

Glossary: tylactone = (4R,5S,6S,7S,9R,11E,13E,15S,16R)-7,16-diethyl-4,6-dihydroxy-5,9,13,15-tetramethyloxacyclohexadeca-11,13-diene-2,10-dione
dTDP-α-D-mycaminose = dTDP-3,6-dideoxy-3-dimethylamino-α-D-glucopyranose
Other name(s): tylM2 (gene name)
Systematic name: dTDP-α-D-mycaminose:tylactone 5-O-β-D-mycaminosyltransferase
Comments: 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.
