Nitrites 208-215 ubiquinol oxidase 1, mitochondrial Nicotiana tabacum 38-41 27987212-9 2017 Hence the ETC, likely the Q-cycle of Complex III generates NO from nitrite, and AOX reduces this activity by acting as a non-energy-conserving electron sink upstream of Complex III. Nitrites 67-74 ubiquinol oxidase 1, mitochondrial Nicotiana tabacum 80-83
