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 important reason that the antitumor anthracycline

The biosynthesis of the iron-molybdenum cofactor (FeMo-co) of dinitrogenase was investigated using99Mo to follow the incorporation of Mo into precursors. 99Mo label accumulates on dinitrogenase only when all known components of the FeMo-co synthesis

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 for NifEN complex organization and function, the com

The products of the nifN and nifE genes of Azotobacter vinelandii function as a 200-kDa α2β2 tetramer (NIFNE) in the synthesis of the iron-molybdenum cofactor (FeMo-co) of nitrogenase, the enzyme system required for biological nitrogen fixation. NI

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 unable to lyse Listeria -infected macrophages un

The iron-molybdenum cofactor (FeMo-co) of nitrogenase contains molybdenum, iron, sulfur, and homocitrate in a ratio of 1:7:9:1. In vitro synthesis of FeMo-co has been established, and the reaction requires an ATP-regenerating system, dithionite, moly

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 neutrophils. We observed no substantial difference in kill

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 mice. Using the EGD strain for subsequent experimen

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 protection were observed in all strains tested. The
