It one of the so-called "Abi" systems for "Abortive infection" discovered in the 90's in research related to the dairy industry :ref{doi=10.1016/j.mib.2005.06.006}. Even though, their name correspond to abortive infection, their mechanism of action does not necessarily correspond to an abortive infection.
Abik is a single gene protein containing a reverse transcriptase domain. This defense system is part of wider defense system family named DRT (for **D**efense associated **R**everse **T**ranscriptases) :ref{doi=10.1093/nar/gkac467}. The other system from this class are : [DRT]{/defense-systems/drt}, [Rst_RT_Nitralase_TM]{/defense-systems/rst_rt-nitrilase-tm}, [AbiA]{/defense-systems/abia}, [AbiP]{/defense-systems/abip2} and [AbiK]{/defense-systems/abik}.

## Molecular mechanism
As far as we are aware, the molecular mechanism is unknown. For all the system of the DRT family, very few things are known for the mechanism.
