Abstract
Here we present the complete genome sequence of A. vinelandii DJ and discuss what the genome has revealed about the organism's ability to protect oxygen-sensitive processes. A. vinelandii has been cited as having one of the highest respiratory rates of any known bacterium. Diazotrophic growth under aerobic conditions is possible because A. vinelandii can adjust oxygen consumption rates to help maintain low levels of cytoplasmic oxygen, which is otherwise detrimental not only to nitrogenase but also to other oxygen-sensitive enzymes expressed by A. vinelandii. This phenomenon is called respiratory protection. In this work, we identify unique features of the A. vinelandii genome that help to explain the coexistence of oxygen-sensitive reactions and strict aerobic metabolism.
