IntEnz Enzyme Nomenclature


Accepted name:
aklavinone 7-L-rhodosaminyltransferase
Other names:
aklavinone 7-β-L-rhodosaminyltransferase
dTDP-β-L-rhodosamine:aklavinone 7-α-L-rhodosaminyltransferase
Systematic name:
dTDP-β-L-rhodosamine:aklavinone 7-α-L-rhodosaminyltransferase (configuration-inverting)



Isolated from the bacterium Streptomyces galilaeus. Forms a complex with its accessory protein AknT, and has very low activity in its absence. The enzyme can also use dTDP-2-deoxy-β-L-fucose. Involved in the biosynthesis of other aclacinomycins.
