Part:BBa_K3183000

Erythromycin Constitutive Promoter

P-erm is a constitutive promoter which can be used in Lactobacillus reuteri 10023C, and may have uses in other Lactobacillus species. It has also been shown to be functional in E. coli.

The promoter is derived from the erythromycin ribosomal methylase (ermB) promoter from the broad-host range plasmid pAMβ1 isolated from Enterococcus faecalis.¹ It was subsequently characterised in six strains of Lactobacillus reuteri and Lactococcus lactisspp. cremoris MG1363.²
