pBAD+strong RBS+E. coli tolC signal sequence+K. pneumoniae tolC
Combination of part BBa_K1406000 (BBa_K206000 + BBa_B0034) the E. coli tolC signaling sequence and the Klebsiella pnuemoniae tolC gene. Transcription is controlled by the arabinose-induced pBAD promoter (BBa_K206000). A strong E. coli RBS (BBa_B0034) controls translation. The signaling sequence is a cleavable N-terminal signaling sequence from E. coli's tolC gene. This is required for trimerization of the TolC monomers as well as insertion into the outer membrane; it forms a chimeric polypeptide with the tolC gene from Klebsiella pnuemoniae TolC trimers form a outer-membrane alpha/beta barrel pore can interface with a variety of molecule pumps to form a transperiplasmic pump. The tolC gene from Klebsiella pneumoniae (part BBa_K1900000) was cloned into a plasmid containing the pTrc promoter. This plasmid was transformed into an E. coli strain lacking a chromosomal copy of tolC. Disk sensitivity assays were performed to determine how well the K. pneumoniae protein would work in an E. coli cell. Sequence and Features
