Arabinose inducible fim operon
This part contains the fim operon under the control of an inducible arabinose promoter. The operon contains six Fim proteins, including FimA, FimI, FimC, FimD, FimF and FimG. When co-transformed with FimH constructs from our project, which have rhamnose-inducible promoters, modified type I pili may be produced. The production of the operon must be initiated by inducing the culture overnight at 0.6 OD at 2% arabinose.
Figure 1 We transformed a plasmid containing the fim operon under the control of the P_Ara promoter. It exhibits flagella on their cell surface, but the electron micrograph shows a suggestion of pili.
This suggests that the P_Ara construct was successful in synthesising pili, without the co-transformation with a FimH construct.
