Comparison of central metabolic features of the Rifle comammox Nitrospira. AMO, ammonia monooxygenase; CAT, catalase; CLD, chlorite dismutase; FDH, formate dehydrogenase; HAO, hydroxylamine dehydrogenase; HURM, hydroxylamine‐ubiquinone reaction module; HYD, group 3b bifunctional NAD(P) hydrogenase; Mnh, multisubunit Na⁺/H⁺ antiporter; NHase, nitrile hydratase; NirK, Cu‐dependent nitrite reductase; SulP, sulfate permease. Asterisks indicate missing genes that potentially result from low‐quality assemblies. The question mark indicates that the exact pathway of nitrite formation from NO is uncertain.
