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. |
