The SURE® System: Subtilin Regulated gene Expression
Bacillus subtilis is an attractive host for gram-positive bacteria as it is non-pathogenic, does not have significant bias in codon usage, and is capable of secreting functional extracellular proteins directly into the culture medium. It is used in a variety of applications, including agricultural, medical and food biotechnology and the production of recombinant proteins.
Controlled gene expression in B. subtilis is a cost-effective alternative to IPTG induced gene expression. This is achieved with the used of subtilin, a small peptide antibiotic of 32 amino acids produced by B. subtilis. Subtilin production and regulation is encoded in the chromosome by a cluster of 9 genes, which are transcribed from two promoters. Subtilin regulates/activates its own biosynthesis via a two-component regulatory system.
Several B. subtilis strains specifically developed for the SURE system are available as well. Additionally, E. coli strain MC1061 can be used with the SURE system.
