Rhizobium japonicum nitrogenase Fe protein gene (nifH) [PDF]
Journal of Bacteriology, 1984 A 12.1-kilobase PstI fragment from Rhizobium japonicum, which contains homology to both the Klebsiella pneumoniae and the Rhizobium meliloti nifH genes, was cloned into vector pHE3 . The nifH -homologous region was localized on the restriction enzyme cleavage map by Southern blot hybridization experiments. DNA fragments overlapping the R.

Characterization of nifH mutations of Klebsiella pneumoniae [PDF]
Journal of Bacteriology, 1988 Nucleotide changes in the nifH gene of Klebsiella pneumoniae were identified by DNA cloning and sequencing of six selected mutant strains. The strains were UN60, C-640-GC----TGC; UN116, C-67-TC----TTC; UN117, G-688-AG----AAG; UN1041, CG-302-C----CAC; UN1678, GC-713-C----GTC; and UN1795, G-439-AG----AAG. Their corresponding amino acid substitutions were

Frontiers in Microbiology, 2023 Nitrogenase in some bacteria and archaea catalyzes conversion of N2 to ammonia. To reconstitute a nitrogenase biosynthetic pathway in a eukaryotic host is still a challenge, since synthesis of nitrogenase requires a large number of nif (nitrogen fixation)

Detection and characterization of cyanobacterial nifH genes [PDF]
Applied and Environmental Microbiology, 1994 The DNA sequence of a 359-bp fragment of nifH was determined for the heterocystous strains Anabaena sp. strain CA (ATCC 33047), Nostoc muscorum UTEX 1933, a Nostoc sp., Gloeothece sp. strain ATCC 27152, Lyngbya lagerheimii UTEX 1930, and Plectonema boryanum IU 594.

nifH genes in the obligate methane oxidizing bacteria [PDF]
FEMS Microbiology Letters, 1988 The hifH gene from Klebsiella pneumoniae, which codes for the Fe protein component of nitrogenase, was used as a probe to detect nifH homologues in total cellular DNA from 13 obligate methane oxidizing bacteria. All but one of those strains that had previously been shown capable of fixing dinitrogen contained sequences homologous to nifH.

nifH amplification for Illumina sequencing v1 [PDF]
, 2020 For metabarcoding purpose, the first step involves the amplification by PCR of a given gene region (for example V4 or V9 region of 18S rRNA gene) or gene itself if its size does not exceed 600bp (the longest fragment size that can be sequenced by Illumina technology).

Widespread Distribution and Expression of Gamma A (UMB), an Uncultured, Diazotrophic, γ-Proteobacterial nifH Phylotype. [PDF]
PLoS ONE, 2015 Marine dinitrogen (N2) fixation studies have focused nearly exclusively on cyanobacterial diazotrophs; however γ-proteobacteria are an abundant component of the marine community and have been largely overlooked until recently.

Diazotrophs Show Signs of Restoration in Amazon Rain Forest Soils with Ecosystem Rehabilitation. [PDF]
, 2020 Biological nitrogen fixation can be an important source of nitrogen in tropical forests that serve as a major CO2 sink. Extensive deforestation of the Amazon is known to influence microbial communities and the biogeochemical cycles they mediate. However,

Non-immune fetal hydrops: etiology and outcome according to gestational age at diagnosis. [PDF]
, 2020 OBJECTIVE: Fetal hydrops is associated with increased perinatal morbidity and mortality. The etiology and outcome of fetal hydrops may differ according to the gestational age at diagnosis.
