BioBricks

Biosurfactator

This year`s BioBrick construction effort will be due to a re-designing and re-assembling of our last year surfactant BioBrick project and improving with a new concept in which we degrade hydrocarbons as well as using the surfactant BioBrick, that we will describe next.

Pseudomonas aeruginosa species of bacteria produce the natural rhamnosyltransferase gene complex (RhlAB). This is the key enzyme responsible for transferring the rhamnose moiety to the b-hydroxyalkanoic acid moiety to biosynthesize rhamnolipid, which is a biomolecule with surfactant properties, but the natural RhlAB gene has illegal restriction sites that make it incompatible with the Assembly Standard Protocol 10, specifically the Pstl1 restriction sites.

The design and construction of the rhamnosyltransferase gene into a BioBrick part was the main goal and achievement of the iGEM Panama Team 2010, but since the beginning of this year’s iGEM project we failed in producing the rhamnolipid compound into our E. coli based-factory, because our last year’s BioBrick appeared to have been denaturalized. We then ordered our BioBrick part BBa_K424018 (iGEM Panama team 2010) from The Registry and once it arrived we ran some tests and we noticed that the part was no longer fitted into the plasmid backbone.

As scientist and iGEMers, we have the responsibility to deliver a functional BioBrick, thus according to iGEM’s competition new slogan, "Quality not Quantity", we have embraced the challenge of re-designing and re-assembling the same BioBrick part from last year in order to comply this new standard based on quality. So we bring the Biosurfactator!!!
