(2022-06-22)Iron (Fe) is essential for most forms of life due to its unique redox and substrate binding properties. It is also dangerous since it can generate reactive oxygen species (ROS). In Saccharomyces cerevisiae, 95 known Fe ...
-
(Texas A&M University, 2004-09-30)The HPr proteins were characterized as folding by a two-state folding mechanism. Here, we present a comparison of the equilibrium and kinetic folding for the HPr protein from Bacillus subtilis, E coli and a key variant ...
-
(2013-08-30)The speciation of iron in intact Jurkat cells and their isolated mitochondria was assessed using biophysical methods. [Fe4S4]^(2+) clusters, low-spin (LS) Fe^(II) heme centers, non-heme high-spin (NHHS) FeII species, ...
-
(1993)E. coli cells expressing a recombinant organophosphate degrading gene (opd) were successfully encapsulated in polyvinyl alcohol (PVA) using cryoimmobilization. Gel matrices were composed of 10% cells in 10% PVA, and electron ...
-
(2022-10-12)Campylobacter jejuni is a pathogenic organism that can cause campylobacteriosis in children and adults. Most commonly, Campylobacter infection is brought on by consumption of raw or undercooked poultry, unsanitary drinking ...
-
(2020-02-19)Campylobacter jejuni is a Gram-negative pathogenic bacterium that is the leading cause of gastroenteritis worldwide. Like many other Gram-negative bacteria, C. jejuni produces a capsular polysaccharide (CPS) that helps ...
-
(2012-11-20)Methyl-accepting chemotaxis proteins MCPs can bind one or more receptor- specific ligands. In the case of the Tar MCP of Escherichia coli (TarEc), a primary attractant ligand is aspartate. Its binding to the periplasmic ...
-
(2017-02-01)The global population is increasing in size and economic affluence, and sustainable intensification of agriculture is necessary to meet projected fuel and food demands without increasing input of limited resources like ...
-
(2020-03-06)Catalytic promiscuity is the coincidental ability for an enzyme to catalyze nonbiological reactions in the same active site as the native biological reaction. Several lines of evidence show that catalytic promiscuity plays ...
-
(2020-01-11)The foci of this work were in characterizing and speciating the low molecular mass (LMM) iron pool in blood. We operationally define this pool as non-proteinaceous iron species with masses <10 kDa. In iron overload disorders ...
-
(2012-10-19)Lysis in cells infected with the ssRNA phage Qbeta is effected by the A2 protein. It was previously shown that a single copy of A2 assembled on the surface of the Qbeta virion inhibited the activity of MurA, which catalyzes ...
-
Clostridioides difficile (C. difficile), the microbe responsible for Clostridioides difficile infection (CDI), is a common nosocomial infection that exerts its pathogenicity primarily by two toxins, TcdA and TcdB. Designed ...
-
(1983)The potential of using biological control agents to promote agricultural by plant scientists. production is now being recognized One agent, Pseudomonas fluorescens strain Pf-5, produces antibiotics which protect cotton ...
-
(Texas A&M University, 2006-10-30)The SmtB/ArsR family of prokaryotic metalloregulators are winged-helix transcriptional repressors that collectively provide resistance to a wide range of both biologically required and toxic heavy metal ions. CmtRMtb is a ...
-
(2019-10-30)The causative agent of Lyme disease Borrelia burgdorferi, is maintained in nature in an enzootic cycle involving a tick vector and a mammalian host. In order to cycle between two vastly different hosts, B. burgdorferi ...
-
(2014-07-10)Sorghum genotypes used for grain production in temperate regions are photoperiod insensitive, while energy sorghum is highly photoperiod sensitive and flowers late in long days, resulting in enhanced biomass accumulation. ...
-
(2018-08-03)Bacillus subtilis is a soil bacterium capable of differentiating into a spore form resistant to both desiccation and heat. Sporulation begins with a single cell possessing two copies of a single, circular genome arranged ...
-
(1979)In this study, cyclic 3':5'-monophosphate phosphodiesterase from human lung tissue was investigated. After a brief review of the literature, some physical properties of the enzyme were characterized. A Heat Lability study ...
-
(2014-03-31)Sorghum bicolor is a subtropical grass grown throughout the world for human consumption, animal feed and for the growing biofuels industry. In this thesis I characterize sorghum stem growth and chemical composition, and ...
-
(2010-01-14)Telomeres are critical for the integrity of eukaryotic genomes. They function to protect chromosome ends from DNA damage surveillance and inappropriate repair. Telomeres are maintained by the specialized ribonucleoprotein ...
