A total of 17 bacterial isolates from northern elephant seals, tentatively classified within the family Pasteurellaceae, were further characterized by genotypic and phenotypic tests. Phylogenetic analysis of partial 16S rRNA and rpoB gene sequences showed that the isolates investigated formed a
A total of 13 Pasteurellaceae isolates from healthy freshwater turtles were characterized by genotypic and phenotypic tests. Phylogenetic analysis of partial 16S rRNA and rpoB gene sequences showed that the isolates investigated formed a monophyletic group. The closest related species based on 16S
OBJECTIVE
The effects of trehalose on cariogenesis by mutans streptococci were investigated.
METHODS
Inhibited effect of trehalose on water-insoluble glucan (WIG) synthesis from sucrose by glucosyltransferase (GTase) of mutans streptococci was assayed. The acid fermentability of trehalose by mutans
A total of 27 bacterial isolates from California sea lions and a walrus tentatively classified within the family Pasteurellaceae was further characterized by genotypic and phenotypic tests. Phylogenetic analysis of partial 16S rRNA and rpoB gene sequences showed that the isolates investigated formed
We report the crystallization and structure determination at 1.85 A of the extracellular, membrane-anchored trehalose/maltose-binding protein (TMBP) in complex with its substrate trehalose. TMBP is the substrate recognition site of the high-affinity trehalose/maltose ABC transporter of the
An efficient strategy toward the synthesis of large-ring cyclodextrin (CD) analogs alternating alpha,alpha'-trehalose disaccharide subunits and pseudoamide segments (cyclotrehalans, CTs), involving a bimolecular macrocyclization reaction as the key step, is reported. NMR and molecular modeling
Concise and efficient strategies toward the synthesis of D2h- and D3h-symmetric cyclodextrin analogues alternating alpha,alpha'-trehalose disaccharide subunits and pseudoamide segments (cyclotrehalans, CTs) are reported. The conformational properties of these cyclooligosaccharides are governed by
In vivo growth of syngeneic tumour cells in the peritoneal cavity was strongly inhibited by intraperitoneal injection of a liposome-encapsulated, mycolic acid-containing glycolipid, trehalose 2,3,6'-trimycolate (TTM), derived from a non-pathogenic, acid-fast bacterium. Gordona aurantiaca. Peritoneal
Immunomodulators of bacterial origin, such as muramyl-dipeptide (MDP) and trehalose dimycolate, are able to stimulate some important biological functions of macrophages, such as their capacity to secrete a monokine, the thymocyte mitogenic protein (TMP), and to limit the growth of mastocytoma cells
It is becoming increasingly apparent that hydrophobic cavities (also referred to as xenon cavities) within proteins have significant functional implications. The potential functional role of these cavities in modulating the internal dynamics of carbon monoxide in myoglobin (Mb) is explored in the
Trehalose dimycolate (TDM) isolated from Nocardia asteroides induced in mice a severely wasted condition known as cachexia. Intraperitoneal injection of mice with five 10 micrograms doses of TDM in mineral oil at intervals of 2 d killed 90% of the animals within 26 d. Death followed a precipitous
Serpin constitute about 10% of blood protein and are associated with mutations that results in aberrant intermolecular linkages which leads to polymer formation. Studies with short peptides have shown promise in depolymerization of serpins however a reactive center loop based peptide also makes the
Surfactants have the potential to overcome natural resistance of MTB to antibiotics which is mediated by barriers that impede the penetration of drugs to their targets. A major component of this barrier is trehalose dimycolate (TDM) which surrounds the bacteria with a thick lipid shield. In this
Infectious diseases are serious public health problems, affecting a large portion of the world's population. A molecule that plays a key role in pathogenic organisms is trehalose and recently has been an interest in the metabolism of this molecule for drug development. The trehalose-6-phosphate
Mice treated with viable Mycobacterium tuberculosis with no glycolipid trehalose dimycolate (TDM) on the outer cell wall (delipidated M. tuberculosis) by intraperitoneal or intratracheal inoculation presented an intense recruitment of polymorphonuclear cells into the peritoneal cavity and an acute
