Immunochemical patterns of distribution of nitrous oxide reductase and nitrite reductase (cytochrome cd1) among denitrifying pseudomonads.

Abstract

The novel multicopper enzyme nitrous oxide reductase from Pseudomonas perfectomarina was purified to homogeneity to study its properties and distribution in various pseudomonads and other selected denitrifying genera by immunochemical techniques. Quantitation of immunochemical crossreactivity by micro-complement fixation within the denitrifying pseudomonads of Palleroni's ribosomal ribonucleic acid group I corresponded to the taxonomic positions established by nucleic acid hybridization. The assignment of P. perfectomarina to the stutzerigroup (as strain ZoBell) was consolidated by immunochemical crossreactivity based on nitrous oxide reductase. Crossreactivity of nitrite reductase (cytochrome cd1) with a respective P. perfectomarina rabbit antiserum was limited to strain DSM 50227 of P. stutzeri; although it could not contribute information towards broader relationships within rRNA group I, it lent further prove to the unity of these two species.
