The Eleos system was previously described as the Dynamins-like system in (Millman et al, 2022).
## Description
\The Eleos (for the greek goddess of mercy) system was previously described as the Dynamins-like system in :ref{doi=10.1016/j.chom.2022.09.017}. It is formed by the LeoA and LeoBC proteins. LeoBC has been found to be analogous to GIMAPs (GTPases immunity-associated proteins), that are interferon inducible :ref{doi=10.1101/2022.12.12.520048}. LeoA in *E. coli* ETEC H10407 localises to the periplasm and has been suggested to potientiate bacterial virulence. Its crystal structure has been solved :ref{doi=10.1371/journal.pone.0107211}. Eleos from *Bacillus vietnamensis* NBRC 101237 has been found to protect against jumbo-phages in *Bacillus subtilis* :ref{doi=10.1016/j.chom.2022.09.017}.
## Molecular mechanism
As far as we are aware, the molecular mechanism is unknown.
## Example of genomic structure
The Eleos is composed of 4 proteins: LeoA, LeoBC, LeoB and LeoC.
The Eleos system is composed of 2 proteins: LeoA and, LeoBC. Sometimes, the system is in three genes: LeoA, LeoB and LeoC.
