title: Ubiquinone in hydrogen metabolism by Azotobacter vinelandii.
abstract: Extraction with n-heptane abolished over 95% of the NADH oxidase and the hydrogenase activity in membrane preparations from Azotobacter vinelandii. Incorporation of ubiquinone-8 or plastoquinone restored each reaction to about 55% of its original activity.
