Other name(s): |
SpnQ; TDP-4-keto-2,6-dideoxy-D-glucose 3-dehydrase |
Systematic name: |
dTDP-4-dehydro-2,6-dideoxy-α-D-glucose hydro-lyase (dTDP-2,3,6-trideoxy-α-D-hexopyranose-forming) |
Comments: |
A pyridoxal 5′-phosphate protein. The enzyme, isolated from the bacterium Saccharopolyspora spinosa, participates in the biosynthesis of forosamine. Requires ferredoxin/ferredoxin reductase or flavodoxin/flavodoxin reductase [1]. |
