Aquatic nitrous oxide reductase gene (nosZ) phylogeny and environmental distribution.

ABSTRACT: Nitrous oxide (N₂O) is a potent greenhouse gas and a major cause of ozone depletion. One-third of atmospheric N₂O originates in aquatic environments. Reduction of N₂O to dinitrogen gas (N₂) requires the nitrous oxide reductase enzyme, which is encoded by the gene nosZ. Organisms that contain nosZ are the only known biological sinks of N₂O and are found in diverse genera and a wide range of environments. The two clades of nosZ (Clade I and II) contain great diversity, making it challenging to study the population structure and distribution of nosZ containing organisms in the environment. A database of over 11,000 nosZ sequences was compiled from NCBI (representing diverse aquatic environments) and unpu
