SRRz+rrnb terminater

The SRRz gene codes maybe three protein S,R,Rz.The product of S gene would cause lesions on the cytoplasmic membrane through which the product coded by the R gene escapes to the periplasm and causes murein-degrading, while the Rz gene’s product may be an endopeptidase that can cleave the oligopeptide crosslinks in the peptidoglycan and/or between peptidoglycan and the outer membrane.

 ===Usage and Biology===
   We use this part to make a high-efficiency biosensor. It can combine with many detecting module to make a detecting device.
+We have developed the metal detecting module (BBa_K2360003) . Combining the lysis module and detecting module, we have constructed  devices which can respond to mercury ion.
+Because the lysis gene will be expressed when the detecting module makes a response to the metal ions, which will make bacterial cleavage, resulting in the decrease of OD600, we measured the growth curve of our engineering bacteria in different concentration of metal ions to prove its function.

+As shown in the growth curves of E. coli with mercury detecting device (figure 2), the growth rate of E. coli BL21 is decline obviously after adding the concentration of Hg<sup>2+</sup> from 10<sup>-5</sup>M to 10<sup>-7</sup>M, indicating this part's  high-efficiency of lysis.
