p68

p68 is a plasmid that can be used to assay promoter activity in Aspergillus nidulans. It contains the lacZ gene, the TtrpC terminator, a USER cassette, an argB marker cassette for selection, an ori for propagation in E. coli, and an ampR resistance cassette. It also contains up- and down stream regions for targeting to a specific site in the chromosome called IS1 situated 202 bp downstream of AN6638 and 245 bp upstream of AN6639. For homologous recombination to occur gene-targeting substrates have to contain these large homologous sequences around 1500 bp to ensure the targeted integration (1).

To insert a promoter by USER cloning p68 should be digested with AsiSI 2-8 hours and afterwards nicked with Nb.BstI for 1-3 hours. Instructions on how to perform the USER cloning and transformation of A. nidulans can be found [http://2011.igem.org/Team:DTU-Denmark-2/Team/Protocols#USER%20cloning here].

DTU-Denmark-2 2011 Plasmid map of p68. After digestion of the USER cassette a promoter of interest can be inserted.

Usage and Biology

This plasmid was successfully used to characterize the A. nidulans promoters PalcA and DMKP-P6. Sequence and Features
