Abstract
This invention relates to the isolation of nucleic acid fragments from Pseudomonas sp. strain G-179 that encode periplasmic nitrate reductase and nitric oxide reductase enzymes. The enzymes are useful in denitrification reactions and for the identification of other denitrifying bacteria. In addition, this invention also relates to the construction of chimeric genes encoding all or a substantial portion of a bacterial nitric oxide reductase or a bacterial periplasmic nitrate reductase enzymes, in sense or antisense orientation, wherein the expression of the chimeric genes results in production of altered levels of the nitric oxide reductase or periplasmic nitrate reductase in a transformed host cell.
