Accepted name: aclacinomycin-T 2-deoxy-L-fucose transferase
Reaction: dTDP-2-deoxy-β-L-fucose + aclacinomycin T = dTDP + aclacinomycin S
Glossary: idarubicin = (7S,9S)-9-acetyl-7-(3-amino-2,3,6-trideoxy-β-L-lyxo-hexosyloxy)-6,9,11-trihydroxy-7,8,9,10-tetrahydrotetracene-5,12-dione
aclacinomycin S = 7-O-(2-deoxy-α-L-fucosyl-(1→4)-rhodosaminyl)aklavinone
aclacinomycin T = 7-O-(α-L-rhodosaminyl)aklavinone
Other name(s): AknK
Systematic name: dTDP-2-deoxy-β-L-fucose:7-(α-L-rhodosaminyl)aklavinone 2-deoxy-α-L-fucosyltransferase
Comments: The enzyme, isolated from the bacterium Streptomyces galilaeus, is involved in the biosynthesis of other aclacinomycins. Also acts on idarubicin. It will slowly add a second 2-deoxy-L-fucose unit to aclacinomycin S in vitro.
