Description
This is a composite part comprising a constitutive promoter, which is the tatABCD promoter from E. coli K-12, driving production of the PduA and PduB proteins from Salmonella enterica serovar Typhimurium LT2 (identical to part BBa_K562003) AND proteins PduT and PduU. These are all components of the Salmonella bacterial microcompartment (BMC). The PduB and PduU gene product carry C-terminal 6-His affinity/epitope tags. Production of the PduB and PduU proteins has been verified by Western immunoblotting (anti-penta-His) and production of PduA, PduB, PduT and PduU have been confirmed by 35S-Met labelling. The proteins have also been purified from E. coli by immobilised metal affinity chromatography (IMAC) and identified by tryptic peptide mass fingerprinting. The construct is cloned as an EcoRI / PstI fragment into pSB1C3. The clone is also known as pSB-ABTU in the Sargent Laboratory, Dundee, UK.
Notes
Native PstI sites in pduB and pduU were removed by site-directed mutagenesis. The fragment also carries an engineered BamHI site at its extreme 3' end.
