This device allows for the IPTG-inducible expression of lacZα peptide which in the presence of Xgal in the medium and chromosomal lacZΔM15 produces blue-coloured colonies. The device was used as an expression vector. SmaI restriction sites flank the lacZ alpha coding sequence. Cutting the part with this enzyme allows for the in-frame insertion of any desired protein coding sequence that contains the splice-in flanking sequences (they can be found in the design section).
BBa_K1807000 was designed as a blue-white screening device that would also be easily used in Gibson Assembly. Surrounding the lacZ alpha coding sequence are two SmaI restriction sites (CCC/GGG). SmaI is a blunt-end endonuclease- we used it to simulatenously linearize our vector and remove the lacZ alpha coding sequence. Our BioBricks contained overhangs that make them compatible with the SmaI-digested BBa_K1807000. The overhang sequences used to make this part are as follows:
- BBa_K1807000 Assembly 5'end Overhang (complementary to pSB1C3): cgctaaggatgatttctgGAATTCGCGGCCGCTTCTAGAG
- BBa_K1807000 Assembly 3'end Overhang (complementary to pSB1C3): TACTAGTAGCGGCCGCTGCAGtccggcaaaaaagggcaag The subparts of the device are as follows: BBa_R0011, BBa_B0034, BBa_E0038, BBa_B0015.

This part codes for the exopolyphosphatase (PPX) enzyme of Escherichia coli. PPX is able to release phosphate residues from the ends of a polyphosphate chain.

This part is a protein coding device containing the Polyphosphate Kinase (PPK) gene from Escherichia coli. PPK produces polyphosphate, more specifically PPK catalyzes the reversible conversion of the γ-phosphate of ATP to the end of the polyphosphate chain.
