The RosmerTA system was found to have antiviral activity and named after Gallo-Roman goddess of fertility by Millman et al. 2022 :ref{doi=10.1016/j.chom.2022.09.017}.
## Molecular mechanisms
The RosmerTA system encodes a Zn-peptidase and a toxin of unknown function :ref{doi=10.1016/j.chom.2022.09.017} and was later found to induce membrane depolarization :ref{doi=10.1073/pnas.2305393120}.
## Example of genomic structure
The RosmerTA is composed of 2 proteins: RmrT and RmrA.
