Part:BBa_K322140

lac promoter + luxAB

The first 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 the second part, which is LuxAB coding, has a known gene sequence of luxCDAB(F)E, where lux A and lux B code for the components of luciferase, and the lux CDE codes for a fatty acid reductase complex that makes the fatty acids necessary for the luciferase mechanism (Meighen, 1991).
