The B. subtilis genome sequence was obtained from the SubtiWiki (http://subtiwiki.uni-goettingen.de/) and BioCyc (http://bsubcyc.org/) databases. The E. coli K-12 MG1655 genome sequence was obtained from the E. coli K-12 project website (http://www.xbase.ac.uk/genome/escherichia-coli-str-k-12-substr-mg1655). The sequences of the standard DNA parts were obtained from the Registry of Standard Biological Parts (http://parts.igem.org/Main_Page). Sequencing was performed by Source Bioscience (Cambridge, UK). Sequences were compared employing TBLASTX, BLASTN [32], and position-specific iterated BLAST (PSI-BLAST) [33] from the National Center for Biotechnology Information (NCBI) website (http://ncbi.nlm.nih.gov).
