This domain is found in Methyl-accepting chemotaxis sensory transducer, class 40H from Geobacter sulfurreducens (Mcp40H-20, Swiss:Q74EM7) and similar proteins predominantly from proteobacteria. This entry represents the periplasmic c-type heme-containing sensor domain, which is located between two transmembrane helices near the N terminus of the protein. This domain adopts a PAS-type domain fold with two helical segments followed by a four-stranded beta-sheet [1].	Domain
