Name
aklavinone 7-L-rhodosaminyltransferase;
AknS/AknT;
aklavinone 7-beta-L-rhodosaminyltransferase;
dTDP-beta-L-rhodosamine:aklavinone 7-alpha-L-rhodosaminyltransferase
Class
Transferases;
Glycosyltransferases;
Hexosyltransferases
Sysname
dTDP-beta-L-rhodosamine:aklavinone 7-alpha-L-rhodosaminyltransferase (configuration-inverting)
Reaction(IUBMB)
dTDP-beta-L-rhodosamine + aklavinone = dTDP + aclacinomycin T [RN:R09331]
Reaction(KEGG)
R09331
Substrate
dTDP-beta-L-rhodosamine [CPD:C18643];
aklavinone [CPD:C12424]
Product
dTDP [CPD:C00363];
aclacinomycin T [CPD:C18634]
Comment
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-beta-L-fucose. Involved in the biosynthesis of other aclacinomycins.
