 # Gao_Hhe
+
+## Description
+The Gao_hhe system is composed by a single protein. It was predicted through a guilty by association approach independent of domain annotations and validated in a heterologous system :ref{doi=10.1093/nar/gkad317}. It contains a predicted helicase and a Vsr (very short patch repair) endonuclease domain :ref{doi=10.1093/nar/gkad317,10.1128/jvi.00599-23}. 
+
+## Molecular mechanisms
+As far as we are aware, the molecular mechanism is unknown. 
+
 ## Example of genomic structure
 
 The Gao_Hhe system is composed of one protein: HheA.
