Rhamnolipid production
This part encodes two enzymes, rhlA and rhlB (BBa_K653000) designed by Panama 2011, for biosynthesis of rhamnolipid. The enzymes are under T7 promoter with medium strengh and a strong ribosomal binding site (BBa_K613010), and stopped with a double terminator (BBa_B0015).
The promoter had the second highest efficiency as shown by EPFL team 2011 (https://parts.igem.org/Part:BBa_K613010:Experience).

Usage and Biology
The biosynthesis of rhamnolipid is relatively simple. It only needs two enzymes which catalyse sequential reaction. The first enzyme, rhamnosyltransferase A (rhlA), which catalyse the dimerisation of two b-hydroxyacyl-ACP chains to make 3-(3-hydroxyalkanoyloxy)alkanoic acids (HAAs). The HAA will form the lipid moiety of the rhamnolipid. Rhamnosyltransferase B, rhlB, will then join TDP-l-rhamnose with HAA to produce mono-rhamnolipid.
Because Escherichia coli can synthesize both rhamnose and fatty acid, the addition of these two enzymes will be sufficient to give the bacteria the ability to synthesize rhamnolipid.
