 # Olokun
+
+## Description
+
+The system Olokun  is composed of 2 genes OloA (Adaptin_N domain) and OloB (nuclease domain) of unknown function.
+This system was experimentally validated in _Escherichia coli_ and protects against LambdaVir and SECphi27 infection.
+
+The system is named after a revered deity of the Yoruba religion, associated with the deep sea and depicted as an enormously powerful figure. They are believed to posses immense wealth, are associated with health, fertility and prosperity, and revered for their ability for inducing profound transformation and renewal.
