Mechanism of ferric enterobactin transport through Escherichia coli FepA: The evolution of a bacterial venus flytrap.
(2001)
The TonB-dependent, energy dependent ferric siderophore transporters of the gram-negative bacterial outer membrane possess a unique architecture: Their N-termini fold into a globular domain that lodges within, and physically ...
Local structures and conductivity in polyethylenimine and polyphosphazene polymer electrolytes.
(2002)
Linear polyethylenimine (LPEI) is structurally analogous to poly(ethylene oxide), with an N-H group in place of the ether oxygen. LPEI systems with dissolved lithium and sodium triflate were prepared and characterized via ...
SYNTHESIS OF STRUCTURAL MODELS OF NON-HEME DIOXYGENASES. MIMICS OF THE 3-His-1-CARBOXYLATE TETRAD
(2009)
Metalloenzymes catalyze various reactions and in particular dioxygenases insert dioxygen into organic substrates. Since these enzymes usually utilize histidines as ligands for the metal cofactor, we focused our attention ...
Testing recently-developed molecular dynamics protocols for structure prediction of polypeptides and prion proteins.
(2007)
Two MD protocols were recently developed that allow a polypeptide to search the PE surface in search of the global PE minimum, which should correspond to the experimental structure. alpha-helical secondary structures have ...
BIOCHEMISTRY OF HEMIN UPTAKE IN LISTERIA MONOCYTOGENES AND THE FUCTION OF TONB IN ESCHERICHIA COLI
(2009)
Iron is an essential metal element for the metabolism pathway of most microorganisms. For pathogens, iron is also an important factor for virulence. But in the host body, the availability of free iron is very low. Iron ...
Sequencing and comparative genomics of Leptospira interrogans serovar pomona and Leptospira kirschneri serovar grippotyphosa.
(2007)
Virulence genes that include methyl-accepting chemotaxis protein, flagellar basal body-associated protein, flagellar motor switch protein, Lig A protein, thermolysin, multiple antibiotic resistance protein, acriflavine ...
SITE-DIRECTED MUTAGENESIS AS A PROBE OF NAD+-BINDING SITE IN MALIC ENZYME
(2008)
The mitochondrial NAD-malic enzyme catalyzes the oxidative decarboxylation of malate to pyruvate and CO2. The role of the dinucleotide substrate in oxidative decarboxylation is probed in this study using site-directed ...
Sequence and analysis of two regions of mouse chromosome 1 involved in interferon response and bone mineral density regulation.
(2002)
The second region of mouse chromosome Iq corresponds to a Quantitative Trait Locus (QTL) of Bone Mineral Density (BMD), and is located near the Ifi200 gene cluster. Bone mineral density is the strongest determinant of ...
Selective methods for the synthesis of highly-substituted cyclopentadienyl and indenyl ligands.
(2003)
Annulation methods involving cyclization of five-membered rings are regioselective approaches to highly substituted indenyl and cyclopentadienyl ligands for use in metallocene catalysts. The object of our research has been ...
Expression profiles and the identification of the clock-controlled genes in two time-of-day-specific cDNA libraries of Neurospora crassa.
(2001)
In the group of genes that were detected from both cDNA libraries, the highest three of the top ten highly expressed genes were clock-controlled genes (ccgs). That these ccgs are so highly expressed in Neurospora implies ...
