Broad-Host-Range Toolkit

The Broad-host-range toolkit (BTK) is a Golden-Gate compatible toolkit of genetic parts designed for working with newly isolated, non-model bacteria. Like the yeast toolkit, it relies on type IIS enzymatic assembly of Type 1-8 parts with defined nucleotide overhangs into complete vectors. The toolkit includes broad-host-range (BHR) promoters and a BHR plasmid backbone that is replicated in diverse Gram-negative and Gram-positive hosts. BTK plasmids possess an origin of transfer (oriT), and can be delivered by conjugation or electroporation. Here we describe example protocols and use cases of the BTK. BTK parts will be deposited and available from Addgene. If you use the BTK parts or these protocols in your work, please cite: .

Detailed description of BTK components and Parts List

BTK Protocols

Design a new part Design overhangs for the amplification of a new custom part to be assembled into a part plasmid.

Assemble a new part plasmid Assemble a new custom part plasmid following amplification with part specific overhangs.

Build a first-stage plasmid from existing BTK parts If the BTK contains all the parts you need, you can build a complete plasmid with a single BsaI reaction.

Build a second-stage plasmid Assemble multiple first-stage transcriptional unit plasmids.

Build a plasmid for CRISPRi gene suppression

Build a plasmid for disruption or knockout of bacterial genes

Deliver plasmids via conjugation into new hosts
