Design Notes

The promoter, RBS, and codon frequency of the circuit are optimized for protein expression in E. coli. However, the P2 promoter shows a high background expression in E. coli, making the device unable to conduct its designated function in E. coli. For a modified version for the expression in B. subtilis, see BBa_K4593021.

Source

LysDZ25 is from bacteriophage DZ25[1], LysGH15 is from Bacteriophage GH15[2], and ClyC is a hybrid endolysin with CBD of LysPALS1 and EAD of LysSA12[3]; Spn1s_LysRZ is from bacteriophage SPN1S[4].

The QS system is from the S. aureus genome, contributed by iGEM07_Cambridge.
