Constitutive promoter family
Parts J23100 through J23119 are a family of constitutive promoter parts isolated from a small combinatorial library. J23119 is the "consensus" promoter sequence and the strongest member of the family. All parts except J23119 are present in plasmid J61002. Part J23119 is present in pSB1A2. This places the RFP downstream of the promoter. Reported activities of the promoters are given as the relative fluorescence of these plasmids in strain TG1 grown in LB media to saturation. See part BBa_J61002 for details on their use.

These promoter parts can be used to tune the expression level of constitutively expressed parts. The NheI and AvrII restriction sites present within these promoter parts make them a scaffold for further modification. JCAraw

 ===Usage and Biology===
 <p> Three parts in this collection have been further characterised by Manchester iGEM 2017 through microscopy. The Manchester team used BBa_J23104, BBa_J23105 and BBa_J23108 to control expression of the bacterial micro-compartment localisation tag, PduD(1-10). This is evidenced through fluorescence microscopy shown below. This data is also documented on https://parts.igem.org/Part:BBa_K2213006, https://parts.igem.org/Part:BBa_K2213007, and https://parts.igem.org/Part:BBa_K2213008.</p>
