taken from ToxR/lambda phage paper A. Modular structure of lambda-ToxR chimeric proteins. Amino acids 1-132 of phage lambda repressor (diamond) were fused to amino acid 12 of ToxR. lambda-ToxR-PhoA had the same C-terminal fusion junction as lambda-ToxR, and in addition, fused alkaline phosphatase sequences (oval) to ToxR amino acid 212. lambda-ToxR-C-term fused the amino-terminal domain of lambda repressor 12 amino acids before the transmembrane domain of ToxR. The ToxR transmembrane domain is represented by the narrow region with squiggly lines.

B. Modular components of the chimeric protein constructed by Kolmar et al. (1995). Amino acids 1-210 of ToxR were used as the basis for most chimeric proteins, except those deleted for ToxR hydrophobic transmembrane residues.
