RosmerTA

Contributors: Lucas Paoli, Gemma Atkinson

Description

The RosmerTA system was found to have antiviral activity and was named after the Gallo-Roman goddess of fertility by Millman et al. 2022 (N/A) .

Molecular mechanisms

The RosmerTA system encodes a Zn-peptidase and a toxin of unknown function (N/A) . One toxin representative has been found to induce membrane depolarization (N/A) .

Example of genomic structure

The RosmerTA is composed of 2 proteins: RmrT and RmrA. The toxin can vary in sequence and structure.

Here is an example found in the RefSeq database:

The RosmerTA system in Paucibacter sp. KCTC 42545 (GCF_001477625.1, NZ_CP013692) is composed of 2 proteins RmrT_2662548665 (WP_231741552.1) RmrA_2662548665 (WP_058719324.1)

Distribution of the system among prokaryotes

Among the NaN complete genomes of RefSeq, the RosmerTA is detected in NaN genomes (NaN %). The system was detected in NaN different species.
