 # Lit
+
+## Description
+
+Lit was first identified in 1989 :ref{doi=10.1128/jb.169.3.1232-1238.1987}, stands for late inhibitors of T4, and was found to inhibit phage T4 in Escherichia coli (K12). The Lit gene is found in the e14 cryptic prophage :ref{doi=10.1128/jb.170.5.2056-2062.1988}. Lit is also partially active against other T-even phages :ref{doi=10.1073/pnas.91.2.802}.
+
+## Molecular mechanisms
+
+The Lit system detects cleaves EF-Tu translation factor :ref{doi=10.1073/pnas.91.2.802} at a late stage of phage maturation, when the major capsid protein binds to EF-Tu and triggers its cleavage by Lit :ref{doi=10.1074/jbc.M002546200}. As a result, the translation is inhbited, which ultimately leads to cell death. Lit is part of the abortive infection category of defense systems.

 ## Example of genomic structure
 
 The Lit system is composed of one protein: Lit.
