 # FS_HsdR_like
 
-## To do 
+## Description
+
+FS_HsdR_like or HsdR_like was discovered in 2022 :ref{doi=10.1016/j.cell.2022.07.014} inside the PICI KpCIC51 in *Klebsiella pneumoniae*.
+
+The HsdR_like system is also effective for blocking conjugation.
+
+The HsdR_like system is composed of tree genes. A first protein encoding a DUF6731 domain and named after it. An hypothetical protein and the HsdR protein with an N terminal HEPN domain and C terminal Zn finger domain.
+
+## Molecular mechanism
+
+As far as we are aware, the molecular mechanism is unknown.
 
 ## Example of genomic structure
