 # Wadjet
+
+## Description
+Wadjet is a defense system discovered in 2018 :ref{doi=10.1126/science.aar4120}. This system is named after the goddess [Wadjet](https://en.wikipedia.org/wiki/Wadjet) matron and protector of the lower Egypt.
+
+This system was discovered using the [defense island](/general_concept/defense-islands) concept :ref{doi=10.1126/science.aar4120}. However, this system do not show any activity against phages, this system provides a resistance against plasmid transformation :ref{doi=10.1126/science.aar4120,10.1016/j.molcel.2022.09.008}.
+
+This system is composed of 4 genes: JetA, JetB, JetC and JetD. JetA, JetB and JetC were found to be related to MukF, MukE and MukB :ref{doi=10.1126/science.aar4120,10.1098/rstb.2004.1606} housekeeping genes. JetC, related to MukB is a SMC containing protein.

+
+### Molecular mechanism
+The anti-plasmid activity Wadjet was shown to be a DNA cleaving mechanism specific to close circular DNA :ref{doi=10.1098/rstb.2004.1606}.
+
+The JetABC complex will act as the sensor detecting using topology sensing the foreign DNA.
+JetD protein is a homodimeric endonuclease that cleaves double stranded DNA.
+JetD need to be in contact with the JetABC complex to be able to cleave DNA.
+
+The mechanism suggested by :ref{doi=10.1098/rstb.2004.1606} is that the complex will bind to the DNA and will extrude loops similarly to Muk and other SMC proteins :ref{doi=10.1126/science.abm4012,10.1126/science.abb0981} that will then be cleave by JetD.
