Camp +1 mutation.

Increased plasmid copy number. Increased P2 extension, stabilizes secondary structure in promoter.

Plasmid Copy Number and Expression - Alma 2022

We created a series of mutants of BBa_J04450 in the origin of replication, and wanted to both quantify the copy number and see the effect the copy number has on gene expression.

We found that, although this mutation increases plasmid copy number, it actually decreases expression. It could be due to collisions between DNA polymerase (attempting to replicate the plasmid) and RNA polymerase (attempting to transcribe the RFP gene).
