Presence of polyphosphate of low molecular weight in zygomycetes.
نویسنده
چکیده
Polyphosphate of average chain length corresponding to 10 phosphate units was detected in the mycelial extract of zygomycetes. Gel electrophoresis techniques commonly used for the separation and characterization of acidic mucopolysaccharides were successfully used for the detection, purification, and characterization of the polyphosphate.

In vitro biocompatibility of low and medium molecular weight chitosan–coated Fe3O4 nanoparticles
Objective(S): The chitosan - Fe3O4 core - shell nanoparticles were synthesized. The nanoparticles should be coated properly in the shape of core-shell, so that they remain hidden from the body's immune system after coating. Effects of different molecular weight in coating were investigated. Methods: Nanoparticles coated with low and ...
متن کاملMolecular dynamics studies on the denaturation of polyalanine in the presence of guanidinium chloride at low concentration
Molecular dynamic simulation is a powerful method that monitors all variations in the atomic level in explicit solvent. By this method we can calculate many chemical and biochemical properties of large scale biological systems. In this work all-atom molecular dynamics simulation of polyalanine (PA) was investigated in the presence of 0.224, 0.448, 0.673, 0.897 and 1.122 M of guanidinium chlorid...
متن کاملThe molecular composition of the volutin granule of yeast.
The volutin granule was isolated from yeast by disruption of freeze-dried cells in an organic solvent and density-gradient-gradient centrifugation. The granule is composed of two types of macromolecule, a linear-chain polyphosphate and four basic proteins, of molecular weights ranging from 10 000 to 20 000. In the dissolved granule these macromolecules are in a complex that is uniform by hydrod...
متن کاملIsolation of a high molecular weight polyphosphate from Neisseria gonorrhoeae
Neisseria gonorrhoeae, as well as other Neisseriae, produce polyphosphate. This polyphosphate exists in two forms. Approximately half of it is loosely associated with the cells and can be recovered by washing in neutral buffers under conditions in which no significant lysis of the cells is observed. The other half is either intracellular or tightly associated, because it requires digestion of t...
متن کاملPreparation, properties and preclinical pharmacokinetics of low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle
Low molecular weight heparin-modified isoliquiritigenin-loaded solid lipid nanoparticle (LMWH-ISL-SLN) was developed for injective application. The morphological observation, particle diameter and zeta potential of LMWH-ISL-SLN were characterized using transmission electron microscopy (TEM) and a Malvern Zetasizer. Its entrapment efficiency (EE) and drug loading (DL) were determined by ultracen...
