Lac-inducible generator of Lpp-OmpA(46-66)-Streptavidin wild-type + His6tag

This device contains a lac promoter and strong ribosome binding site for lac-inducible expression of the fusion protein of Lpp signal peptide, OmpA aa46-66, and streptavidin wild-type + His6 tag. This expression should display streptavidin on the cell surface of E. coli.

NOTE ABOUT THE SEQUENCE: The mixed site between parts is 'only' six base pairs, ACTAGA. There is no spacer T or G nucleotide. These spacer nucleotides have been placed in the results for "get selected sequence" as an automatic composite-parts addition for the BioBricks mixed site between assembled parts. However, this does not apply for the two spacer nucleotides betweeon R0010 and B0034, and the one spacer nucleotide after B0034, because those were standard BioBricks.

Possible error in Spring 2008 distribution information

The sequence data for this construct suggest it's on plasmid backbone pSB1A3, not pSB1A2 as the 2008 Spring Distribution states. The bases following the PstI site are 5'-tccggcaaaaaa-3' which matches pSB1A3, while the same section of pSB1A2 reads 5'-gcttcctcgctc-3'.

Also, the 'inconsistent' sequence data is due to the fact that, in order to conform to the composite parts format, an 8 base scar is shown in the 'get selected sequence' readout. The sequencing data is checked against this sequence with the 8-base scars, not the 6-base in-frame scars that are part of the sequencing data. --robere, 11 Sept 2009
