The nifE and nifN gene products from Azotobacter vinelandii form an alpha2beta2 tetramer (NifEN complex) that is required for the biosynthesis of the nitrogenase FeMo cofactor. In the current model(More)
Growth of three clinical isolates (Scott A, Murray B, and F5380) and one laboratory strain (EGD) of L. monocytogenes at 4 degrees C significantly increased their virulence for intravenously injected(More)
BACKGROUND The biological activity of many microbial products requires the presence of one or more deoxysugar molecules attached to agylcone. This is especially prevalent among polyketides and is an(More)
The biosynthesis of the iron-molybdenum cofactor (FeMo-co) of dinitrogenase was investigated using 99Mo to follow the incorporation of Mo into precursors. 99Mo label accumulates on dinitrogenase only(More)
In this study we show that recombinant human IL-1 alpha (rhIL-1 alpha) protects both genetically resistant and susceptible strains of mice against Listeria monocytogenes infection. Similar levels of(More)
In this study, we compared three human isolates (F5380, Scott A, and Murray B) and one laboratory strain (EGD) of Listeria monocytogenes for their resistance to ingestion and killing by human(More)
In this study, we determined whether spleen cells from Listeria monocytogenes-immunized mice were cytolytic for Listeria-infected macrophages. Spleen cells freshly obtained from immunized donors were(More)
The products of the nifN and nifE genes of Azotobacter vinelandii function as a 200-kDa alpha 2 beta 2 tetramer (NIFNE) in the synthesis of the iron-molybdenum cofactor (FeMo-co) of nitrogenase, the(More)
