pBBR1MCS-terminator plasmid
Contents
Description
The pBBR1MCS plasmid is a synthetic plasmid backbone used in various genetic engineering applications in microbial systems. We modified the original pBBR1MCS and added a double terminator rrnBT1-T7Te(BBa_B0015) downstream the Biobrick suffix.
Sequence and Features
This backbone consists of several parts, including promoters, terminators, resistance genes, and prefix and suffix we added.

Origin
It's antibiotic-resistant derivatives of the broad-host-range (bhr) cloning vector.We get the pBBR1MCS-2 plasmid on the addgene, and add a terminator rrnBT1-T7Te(BBa-B0015) to it.
Experimental Characterization and results
We performed double enzyme digestion on the plasmid and obtained a fragment of approximately 5000bp(Fig.2)

Chassis and Genetic Context
We successfully expressed in Shewanella onediensis MR-1.
Potential Applications
1. It can be used in microbial fuel cells to study and enhance the extracellular electron transfer capabilities such as in S. oneidensis.
2. It can be used as a backbone for CRISPR-based genome editing systems, enabling precise genetic modifications.
3. It was used in our project to carry components related to phosphorus metabolism. Our results indicate that this component is a good backbone for carrying phosphorus metabolism related components. So it may be able to be used to solve the problems of regulating the electricity production and phosphorus accumulation of S.oneidensis. Thus providing the possibility for organisms to generate electricity while removing pollution.
