The DNA was amplified from E. coli BL21 genomic DNA using primers based on published sequence (Genbank accession J01636, gi:146575). The annotation shown here is based on that associated with this Genbank entry. The sequence shown here is derived by sequencing the construct.
This part (submitted in pSB1A2) consists of the lac promoter and lacZ' gene, encoding the N-terminal 76 amino acid residues of LacZ, sufficient to complement the lacZ-delta-M15 mutation for blue-white selection on Xgal plates. A SacI site has been introduced at the 3' end, overlapping the XbaI site of the Biobrick prefix. This is designed to be used as a cloning vector for making new biobricks. PCR primers can be designed with a SacI site in one primer and an SpeI site in the other. This removes the necessity for an excessively long non-complementary tail on one primer bearing either the full biobrick prefix or suffix. The PCR product can then be digested with SacI and SpeI for insertion into this plasmid, replacing the Plac-lacZ' cassette. Recombinant plasmids will then be white on IPTG/Xgal plates, whereas any that still contain the original insert will be blue. We have used this strategy to prepare several biobricks, including BBa_J33204, which contains the xylE gene encoding catechol-2,3-dioxygenase. (For making biobricks that contain lacZ', BBa_J33204 can be used in the same way; in this case, clones with plasmids that still contain xylE will turn yellow on addition of a drop of 10 mM catechol.)

Note that the SacI site overlaps the SpeI site. The Biobrick prefix ends ...TCTAGAG. When this is added to the CTC at the start of the sequence shown here, the SacI site, GAGCTC, is generated.

oriT/LacZ
oriT with lac promoter and lacZ

The oriT sequence was taken from the self-transmissible plasmid RP4. [[Part:BBa_J33207|LacZ]] is available as a part in the registry.
This part was constructed to compare the [[Part:BBa_J01003|oriTr]], which is currently available in the registry to [[Part:BBa_K125320|oriT]] which was recently designed to perform the same function. The oriTr was added to [[Part:BBa_J33207|LacZ]] part so that conjugation could be monitored by blue/white selection.

This part is similar to [[Part:BBa_J01003|J01003]], which has no experience and is much longer. In the process of designing and testing this part, it will be compared to J01003.
