Reductive dehalogenation of the trichloromethyl group of nitrapyrin by the ammonia-oxidizing bacterium Nitrosomonas europaea.
Suspensions of Nitrosomonas europaea catalyzed the reductive dehalogenation of the commercial nitrification inhibitor nitrapyrin (2-chloro-6-trichloromethylpyridine). The product of the reaction was identified as 2-chloro-6-dichloromethylpyridine by its mass fragmentation and nuclear magnetic resonance spectra. A small amount of 2-chloro-6-dichloromethylpyridine accumulated during the conversio...
متن کاملThe Genome of the Ammonia Oxidizing Bacterium Nitrosomonas europaea: Iron Metabolism and Barriers to Heterotrophy
Nitrosomonas europaea is an aerobic lithoautotrophic bacterium that uses ammonia (NH3) as its energy source (3). As a nitrifier, it is an important participant in the N cycle, which can also influence the C cycle. The genome sequence of N. europaea has been annotated and consists of approximately 2460 protein-encoding genes (1). We are continuing to use the genome sequence to explore the geneti...
متن کاملMethane oxidation by Nitrosomonas europaea.
Methane inhibited NH4+ utilization by Nitrosomonas europaea with a Ki of 2mM. O2 consumption was not inhibited. In the absence of NH4+, or with hydrazine as reductant, methane caused nearly a doubling in the rate of O2 uptake. The stimulation was abolished by allylthiourea, a sensitive inhibitor of the oxidation of NH4+. Analysis revealed that methanol was being formed in these experiments, wit...
متن کاملEvolution and functional characterization of the RH50 gene from the ammonia-oxidizing bacterium Nitrosomonas europaea.
The family of ammonia and ammonium channel proteins comprises the Amt proteins, which are present in all three domains of life with the notable exception of vertebrates, and the homologous Rh proteins (Rh50 and Rh30) that have been described thus far only in eukaryotes. The existence of an RH50 gene in bacteria was first revealed by the genome sequencing of the ammonia-oxidizing bacterium Nitro...
متن کاملMultiple copies of genes coding for electron transport proteins in the bacterium Nitrosomonas europaea.
The genome of Nitrosomonas europaea contains at least three copies each of the genes coding for hydroxylamine oxidoreductase (HAO) and cytochrome c554. A copy of an HAO gene is always located within 2.7 kb of a copy of a cytochrome c554 gene. Cytochrome P-460, a protein that shares very unusual spectral features with HAO, was found to be encoded by a gene separate from the HAO genes.
