rfbD
Enables dTDP-4-dehydrorhamnose reductase activity.

Biology

The rfbD encodes the dTDP-4-dehydrorhamnose reductase from Escherichia coli DH10β. And RfbD catalyzes the terminal step of rhamnose biosynthesis pathway by converting dTDP-6-deoxy-l-lyxo-4-hexulose to the final product dTDP-l-rhamnose, which provides precursors of rhamnose for rhamnolipids biosynthesis. (1)

Usage

We used BBa_K081005 to construct the expression system and obtained the composite BBa_K5136233, which is assembled on the expression vector pSB3K3 by standard assembly. The constructed plasmid was transformed into E. coli DH5α, then the positive transformants were selected by kanamycin and confirmed by colony PCR and sequencing.

Characterization

1. Agarose Gel Electrophoresis

After transferring the plasmid into E. coli DH5α, colony PCR was used to certify the plasmid was correct. The expected bands(1414 bp) were obtained at the position around 1500 bp (Fig. 1).
