Human Serum Protein Adsorption onto Synthesis Nano-Hydroxyapatite
The Protein Journal - Tập 31 - Trang 150-157 - 2011
M. Mohsen-Nia, M. Massah Bidgoli, M. Behrashi, A. Mohsen Nia
Adsorption of human serum proteins (Albumin and total protein) onto high purity synthesis nano-hydroxyapatite (HA), Ca10(PO4)6(OH)2, has been studied in a wide temperature range by UV–visible spectrophotometer. Adsorption isotherm is basically important to describe how solutes interact with adsorbent, and is critical in optimizing the use of adsorbent. In the present study, the experimental result...... hiện toàn bộ

Saccharomyces cerevisiae Phosphoenolpyruvate Carboxykinase: The Relevance of Glu299 and Leu460 for Nucleotide Binding
The Protein Journal - Tập 29 - Trang 299-305 - 2010
Estela Pérez, Emilio Cardemil
A homology model of Saccharomyces cerevisiae phosphoenolpyruvate (PEP) carboxykinase (ATP + oxaloacetate ⇄ ADP + PEP + CO2) in complex with its substrates shows that the isobutyl group of Leu460 is in close proximity to the adenine ring of the nucleotide, while the carboxyl group of Glu299 is within hydrogen-bonding distance of the ribose 2′OH. The Leu460Ala mutation caused three-fold and seven-fo...... hiện toàn bộ

Physical and Kinetic Properties of the Family 3 β-Glucosidase from Aspergillus niger Which Is Important for Cellulose Breakdown
The Protein Journal - Tập 23 Số 1 - Trang 11-23 - 2004
Seidle, Heather F., Marten, Ira, Shoseyov, Oded, Huber, Reuben E.
A β-glucosidase (BGS) purified from Aspergillus niger cellulase powder (obtained from Sigma, St. Louis, MO, USA) was characterized. Electrophoresis, size exclusion chromatography, and dynamic light scattering indicated that the enzyme is a dimer of approximately 200 kDa. Five of the seven N-glycosylated oligosaccharides attached to BGS were composed of D-mannoses attached to a β(1-4)-N-acetyl-gluc...... hiện toàn bộ

Kinetics of Histidine Dissociation From the Heme Fe(III) in N-fragment (residues 1–56) of Cytochrome c
The Protein Journal - Tập 23 - Trang 519-527 - 2004
Stefania Abbruzzetti, Cristiano Viappiani, Federica Sinibaldi, Roberto Santucci
We have here investigated the dissociation kinetics of the His side chains axially ligated to the heme-iron in the ferric (1–56 residues) N-fragment of horse cyt c. The ligand deligation induced by acidic pH-jump occurs as a biexponential process with different pre-exponential factors, consistent with a structural heterogeneity in solution and the presence of two differently coordinated species. I...... hiện toàn bộ

Characterization of a Long-Acting Site-Specific PEGylated Murine GM-CSF Analog and Analysis of Its Hematopoietic Properties in Normal and Cyclophosphamide-Treated Neutropenic Rats
The Protein Journal - Tập 39 - Trang 160-173 - 2020
George N. Cox, Ji I. Lee, Mary S. Rosendahl, Elizabeth A. Chlipala, Daniel H. Doherty
Previously we reported that site-specific modification of the human granulocyte-macrophage colony-stimulating factor (GM-CSF) A3C analog with polyethylene glycol (PEG) dramatically improved the pharmacokinetic properties of the protein in rats. However, we could not evaluate the hematological properties of the PEG-A3C protein in rats because human GM-CSF is inactive in rodents. To study the biolog...... hiện toàn bộ
Phosphorylation of Leghemoglobin at S45 is Most Effective to Disrupt the Molecular Environment of Its Oxygen Binding Pocket
The Protein Journal - Tập 34 - Trang 158-167 - 2015
Kaushik Bhar, Atanu Maity, Amit Ghosh, Tanusree Das, Shubhra Ghosh Dastidar, Anirban Siddhanta
In leguminous plants, nitrogenase that catalyzes anaerobic symbiotic nitrogen fixation is protected by the sequestration of O2 by Leghemoglobin (LegH). The modulation of the oxygen binding capacity of Hemoglobin (Hb) by different post-translational modifications is well studied; whereas similar studies on LegH’s O2 binding are not yet benchmarked. Our results show that in vitro serine phosphorylat...... hiện toàn bộ
