pCK314
(Plasmid #110545)

• Purpose: Modified (delta CRP-binding site) rhamnose-inducible promoter, YFP, an E. coli-Synechocystis shuttle vector, chromosomal-integration sites. Allows precise & sustained gene expression in cyanobacteria
• Depositing Lab: John Heap
• Publication: Kelly et al ACS Synth Biol. 2018 Apr 2. doi: 10.1021/acssynbio.7b00435.

Backbone

• Vector backbone: pACYC177
• Backbone size w/o insert (bp): 3941
• Total vector size (bp): 6027
• Modifications to backbone: Addition of two 1000bp sequences with homology to the Synechocystis sp. PCC6803 genome, allowing chromosomal integration. Introduction of the rhaBAD promoter from E. coli with CRP-binding sites removed (allowing inducible expression with L-rhamnose). Introduction of a synthetic RBS and yfp as a reporter. Introduction of rhaS gene from E. coli, the transcriptional activator required for rhaBAD function in Synechocystis.
