Helper construct for NRP-Indigoidine-tagging

This part serves as helper plasmid for efficient cloning of custom <a href="http://2013.igem.org/Team:Heidelberg">non-ribosomal peptide synthetases</a> (NRPSs) that enable labeling of the synthesized non-ribosomal peptides with the blue pigment Indigoidine. NRPS modules can be introduced by Giboson cloning in any desired order. When inserted, they are replacing the ccdB suicide gene located in front of the indigoidine module.
Note: as ccdB is replaced during cloning, only constructs bearing the desired custom NRPS sequences are successfully propagated in E. coli strains such as Top10 or DH5alpha. Thereby, false-positive-rate of clones is reduced to almost to 0 %.
Since the blue pigment Indigoidine can be seen by the naked eye, analytical procedures can be facilitated. Blue colonies indicate synthesis of the synthetic peptide fused to Indigoidine. A thin-layer chromatography can be easily applied to confirm those observations.

To verify the sequence of our construct, colony PCRs, and analytical restriction digests with Pst1 and EcoRI were performed. Assembly overhang regions were correctly sequenced as well.
