CynR deletion mutations. The amino acid regions in CbnR are described in the top row, with the equivalent regions of CynR used to construct deletion fusions described in the second row. The regions included in the fusions are shaded, with the name of the construct on the left (A–J). The immunity of each construct against λKH54 is shown in the right hand column. I = Immunity/Oligomerization; S = Sensitivity/No oligomerization. [Color figure can be viewed in the online issue, which is available at www.interscience.wiley.com.]
