The Hyperspank promoter was designed to be compatible for B. subtilis. It is shorter than the classic one, but is also recognised by E. coli polymerases.

We characterised it with an RFP expression system (PHs-RBS-RFP), into TURBO cells that express LacI to allow the promoter to be the less leacky possible. This system is inducible by IPTG.
