 # SMA
 
 ## Description
-SMA (single-protein MazF-like antiphage system) was identified in a phage-inducible chromosomal island (PICI) found in *Staphylococcus aureus* ref{doi=10.1016/j.cell.2022.07.014}. SMA was shown to inhibit phage infection and to inhibit the formation of new virions after prophage induction.

 ## Molecular mechanisms
-The SMA protein comprises a domain analogous to MazF. MazF a protein that is normally part of the MazEF toxin-antitoxin systems, in which MazF is a toxic endoribonuclease that targets mRNA ref{10.1016/s1097-2765(03)00402-7}.

 As far as we are aware, the precise molecular mechanism of SMA is unknown.
