Glossary: mycaminose = 3,6-dideoxy-3-dimethylamino-glucopyranose
tylonolide = 2-[(4R,5S,6S,7R,9R,11E,13E,15R,16R)-16-ethyl-4,6-dihydroxy-15-(hydroxymethyl)-5,9,13-trimethyl-2,10-dioxooxacyclohexadeca-11,13-dien-7-yl]acetaldehyde
demethyllactenocin = [(2R,3R,4E,6E,9R,11R,12S,13S,14R)-12-{[3,6-dideoxy-3-(dimethylamino)-D-glucopyranosyl]oxy}-2-ethyl-14-hydroxy-5,9,13-trimethyl-8,16-dioxo-11-(2-oxoethyl)oxacyclohexadeca-4,6-dien-3-yl]methyl 6-deoxy-β-D-allopyranoside
Other name(s): tylN (gene name)
Systematic name: dTDP-6-deoxy-α-D-allose:5-O-β-D-mycaminosyltylonolide 23-O-6-deoxy-α-D-allosyltransferase
Comments: The enzyme participates in the biosynthetic pathway of the macrolide antibiotic tylosin, which is produced by several species of Streptomyces bacteria.
