Molecular Microbiology, 2001
This review assembles data from three bodies of literature (bacterial genetics, plastid biogenesis and parasitology) that seldom have much direct cross‐talk. After overcoming terminological complications to sort out microbial nifS from sufS genes, we connect a bacterial operon, recently found to be involved in iron metabolism, the formation of [Fe–S ...

Nif-hybrids of enterobacter: Selection for nif gene integration with chlorate
Molecular and General Genetics MGG, 1983The nif gene group from Klebsiella can be transferred into Enterobacter cloacae by conjugation using Escherichia coli donor cells carrying the composite self-transmissible nif-plasmid pRD1. A small fraction of the hybrids obtained is stable upon prolonged passaging without selection.

nif Gene expression in a Nif+, Fix− Bradyrhizobium japanicum variant
FEMS Microbiology Letters, 1994Bradyrhizobium japonicum USDA 110 has been shown to contain several genetically similar, naturally occurring colony morphology variants. One of these variants, L2-110, although devoid of symbiotic nitrogen fixation, retains significant levels of ex planta nitrogen fixation ability relative to other symbiotically competent USDA 110 variants (MN-110 and ...

Status of NIF mirror technologies for completion of the NIF facility
SPIE Proceedings, 2008The 1600 mirrors required for the National Ignition Facility (NIF) are now coated with the last optics currently being installed. The combined surface area of the NIF mirrors is almost 450 square meters, roughly 3.4 times greater than the surface area of the two Keck primary mirrors. Additionally, the power handling specification of NIF mirrors is 19

Molecular and General Genetics MGG, 1983
The nitrogen fixation (nif)-gene group of Klebsiella can be transferred onto Enterobacter cloacae by conjugation, using Escherichia coli donor cells carrying the composite self-transmissible nif-plasmid pRD1. To enforce integration and stabilisation, in the present study a derivative of pRD1, viz plasmid pCE1, containing the Mu transposon was used ...

Conservation of nif sequences in Frankia
Molecular and General Genetics MGG, 1988Southern blots of Frankia total DNAs were hybridized with nifHDK probes from Rhizobium meliloti, Klebsiella pneumoniae and Frankia strain Arl3. Differences between strains were noted in the size of the hybridizing restriction fragments. These differences were more pronounced among Elaeagnus-compatible strains than among Alnus- or Casuarina-compatible ...

Origin and Evolution of nif Genes
2005Very little is known on the origin and evolution of nif genes, as well as on the molecular mechanisms, such as paralogous duplication and/or domain shuffling, which might have been involved in shaping the nitrogen fixation process. Useful hints on these issues and on the connection of nitrogen fixation with other complex metabolic pathways can be ...

Overproduction of nif KD and nif SUX from Klebsiella Pneumoniae
1984The molybdenum-iron protein and the iron protein from Klebsiella pneumoniae catalyze the reduction of dinitrogen to ammonia. The MoFe-protein, believed to harbour the site(s) for dinitrogen binding, contains 2 bound molybdenum, 30–32 irons and 28 acid-labile sulfurs.

Journal de Physique IV (Proceedings), 2006
The National Ignition Facility neutron imaging system (NIS) is an important diagnostic for understanding ignition experiments at the NIF in late 2010. The goal of the diagnostic is to provide spatially resolved information on the production of prompt and scattered neutrons from imploded ignition targets.
