J23100-B0034-his-rhlA-B0015-J23100-B0034-rhlB-B0015
Responsible for bioproduction of rhamnolipid.
Biology
RhlAB
RhlA, RhlB and RhlC, which are important enzymes to control the production of rhamnolipids, are found almost exclusively in Pseudomonas sp. and Burkholderia sp.¹
Usage
RhlA is used for generating the lipid component of rhamnolipid, RhlB can then catalyze the reaction between HAA and dTDP-l-rhamnose to form mono-rhamnolipid. We ligased two composite parts BBa_K3739046 and BBa_K3739047 together into the expression vector pET-28a(+) by standard assembly, then transferred it into Vibrio natriegens to verify its ability to produce rhamnolipids.
Characterization
1. Agarose Gel Electrophoresis(rhlA)
After transferring the plasmid into Vibrio natriegens, colony PCR was used to certify the plasmid was correct. The expected result was obtained(1305bp).
Fig.1 The result of colony PCR. Plasmid pET-28a(+).
2. Agarose Gel Electrophoresis(rhlB)
After receiving the plasmid from Sangon Biotech®, regular PCR was used to certify the correctness of the plasmid. Target bands (1698 bp) can be observed at the position around 1700 bp (Fig. 2).
