+## Description
+
+RnlAB is a type II toxin-antitoxin system, in which RnlA is the toxin and RnlB the antitoxin :ref{doi=10.1534/genetics.110.121798}.
+
+## Molecular mechanisms
+
+The RnlA toxin has a RNase activity. RnlB (formerly yfjO) is the antitoxin and suppresses the RNase LS activity :ref{doi=10.1534/genetics.110.121798}.
