+## Description
+The Gao_upx 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=10.1126/science.aba0372}. It's been identified as part of a highly conserved core defense hotspot in *Pseudomonas aeruginosa* strains :ref{doi=10.1093/nar/gkad317}. 
+## Molecular mechanisms
+As far as we are aware, the molecular mechanism is unknown. 
 ## Example of genomic structure
 
 The Gao_Upx system is composed of one protein: UpxA.
