 ## Description
+This NLR like system is also known as the bNACHT systems.
+
 Several proteins containing a NACHT module were found to have anti-phage activity. NACHT modules are also found in metazoans, where they play a role in innate immunity. 
 
 bNacht systems have some similarities with other defense systems:
 [CARD_NLR](/defense-systems/card_nlr) , [Rst_TIR-NLR](/defense-systems/rst_tir-nlr), [Avs](/defense-systems/avs).
 
 ## Molecular mechanism
+
 Bacterial NACHT module-containing proteins (bNACHT) encompass a C-terminal sensor, a central NACHT module, and N-terminal effector modules. The N-terminal effectors associated with bNACHT proteins are diverse, and include domains that have been previously described to be involved in other defense systems {doi=10.1016/j.cell.2023.04.015}
 As far as we are aware, the precise molecular mechanism of bNACHT is unknown.
