 # RloC
+
+## Description
+
+RloC is a distant homologue of the tRNALys anticodon nuclease (ACNase) PrrC. RloC shares the ABC ATPase motifs and catalytic ACNase triad with PrrC, but it possesses a unique zinc-hook/coiled-coil insert. This distinctive feature results in its ATPase domain bearing similarity to Rad50 and other DNA repair proteins.Contrary to PrrC RloC is rarely linked to a type I R-M system. RloC activity was not directly demonstrated on phages but hypothesized through its similar features to PrrC :ref{doi=10.1111/j.1365-2958.2008.06387.x}.
+
+## Molecular Mechanism
+RloC was shown to function by tRNA cleavage (wobble nucleotide-excising and Zn++-responsive tRNase) :ref{doi=10.1006/jmbi.1995.0343}. However such activity was not directly shown on a phage. Zinc hook seems to regulate the nuclease function.
+
 ## Example of genomic structure
 
 The RloC system is composed of one protein: RloC.
