215 bp long bindingsite_promoter_bindingsite_RBS is amplified by PCR with dangling end primers with EcoRI-NotI-XbaI restriction site at 5’ and SpeI at 3’ and inserted into a Biobrick compatible vector. The sequence is taken from wildtype Bacillus subtilis.

Forward primer used: GATCTG-GAATTCGCGGCCGCTTCTAGAG-CACAGCGTTCTTTGTAAG (Clamp sequence - Standard Biobrick prefix - first 18 base from the Biobrick)

Reverse primer used: TGTGAC-ACTAGTA-GCCCTCCCGAATGTTGAG (Clamp sequence - SpeI site - last 18 base from the Biobrick)

Spacing between the RBS and downstream CDSs

To make the RBS efficient, 7 bases are needed between the RBS and CDS. The scar between the biobricks will already have the 6 bases and we left one base after the rbs to total it to 7 bases.
