==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.

The sequence is taken from E. coli strain DH5 alpha. Genbank accession number for E. coli MG1655 strain is NC_000913.2

Construction

Plasmid part BBa_J04450 (pSB1AT3) and our construct were treated with EcoRI and SpeI

The backbone and the sspB insert were then ligated
