Superfamily: Histidine kinase NarX, sensor domain

According to InterPro, this sensor domain is found N-terminal in histidine kinase NarX and other sensor proteins, as well as in type IV pilin, PilJ. NarX is a histidine kinase receptor that responds to nitrate and nitrite to effect regulation of anaerobic respiration in various bacteria. DOI:10.1016/j.str.2008.12.013, INTERPRO:IPR029095
