Part:BBa_K3183000:Design
Erythromycin Constitutive Promoter
The part was identified in the article by Lizier et al; the gene was codon optimised for L. reuteri and synthesized by IDT. The part was leter assembled by Gibson Assembly into composite parts such as: BBa_K3183103, BBa_K3183100 etc., which were finally assembled into the pTRKH3 vector (BBa_K3183050), again by Gibson Assembly

Design Notes
This promoter was specifically selected as an ideal promoter for L. reuteri because it conformed to the RF10, RF12, RF21, RF23, RF25, and RF1000 standards.
Source
It is the erythromycin ribosomal methylase (ermB) promoter from the broad-host range plasmid pAMβ1 isolated from Enterococcus faecalis. We ordered the sequence as a gBlock from IDT.
