rose water residues are by-products of rose water industries. these residues do not have any industrial usage and they are returned to soil as crop fertilizer. in this research, the effects of adding rose water distillation residues to soil in different particle sizes and weight proportion were investigated and changes in mechanical strength, and water holding capacity of soil and the growth of...

The GAL4 transcript ional activator protein has long been a favorite for the study of transcription in eukaryotic biology. Genetic studies reveal a modular architecture for the protein with different functions associated with each module [1]. A DNA-binding domain of the protein recognizes and binds to a sequence of DNA termed the Upstream Activating Sequence ( U A S Q ) . Other parts of the pro...

Abstract A neutral ginger polysaccharide fraction (NGP) was isolated from ginger, and its primary structures immunomodulatory activity were investigated. The results showed that NGP had a low molecular weight of 6305 Da. principally consisted glucose (93.88%) together with minor levels galactose (3.27%) arabinose (1.67%). Besides, methylation analysis 1D/2D NMR spectroscopy demonstrated ?-gluca...

In this study, 10 ns molecular dynamics simulations were conducted to determine the optimum length and type of O-glycosylation in the linker domain of glucoamylase from Aspergillus awamori. The linear distance between the Nand C-termini of the linker domain fluctuated rapidly between 105 and 126 Å without adding sugars onto the Thr and Ser residues. Mannose was found to be more favorable to be ...

Insulin receptors of human lymphocytes (IM-9 line) were biosynthetically labeled with [3H]glucosamine, [3H]galactose, [3H]fucose, or [3H]mannose. After solubilization in Triton X-100, cell extracts were immunoprecipitated with serum from a patient containing autoantibodies to the insulin receptor. Na-DodSO4/polyacrylamide gel electrophoresis of the immunoprecipitates under reducing conditions s...

antibacterial drugs used in animal might result in deposition of residues in meat, milk and eggs. the presence of antimicrobial residues in animal-originated food is critical problem in many countries over the years. because, drug residues might result in various health hazards, both actual incidence of reactions and potential hazards perceived by the public, the most countries assess residue o...

Millettia japonica was recently reclassified into the genus Wisteria japonica based on chloroplast and nuclear DNA sequences. Because the seed of Wisteria floribunda expresses leguminous lectins with unique N-acetylgalactosamine-binding specificity, we purified lectin from Wisteria japonica seeds using ion exchange and gel filtration chromatography. Glycan microarray analysis demonstrated that ...

In most organisms, the conversion of -D-galactose to the more metabolically useful glucose 1-phosphate is accomplished by the action of four enzymes that constitute the Leloir pathway (Scheme 1). In the first step of this pathway, -D-galactose is epimerized to -D-galactose by galactose mutarotase. The next step involves the ATP-dependent phosphorylation of -D-galactose by galactokinase to yield...

Isolated rat hepatocytes bind to synthetic flat polyacrylamide matrices containing covalently attached galactose residues in a sugar-specific and concentration-dependent manner. Cell binding is mediated by the asialoglycoprotein receptor and occurs as a threshold response at or above a critical concentration of sugar in the matrix. Hepatocytes in the presence or absence of serum were able to sp...
