Uncoating ATPase catalyzes the ATP-dependent dissociation of clathrin from coated vesicles and empty cages. Following an uncoating reaction, clathrin triskelions are released intact, in a stoichiometric complex with bound uncoating protein. This overall uncoating process was dissected into two partial reactions. In the first, ATP hydrolysis drives the transient displacement of a portion of a tr...

in order to increase grain yield, nitrogen use efficiency (nue) and nitrogen apparent recovery fraction (narf) in wheat (triticum aestivum l.), this experiment was carried out with 5 or 6 treatments and 3 or 4 replications in 14 locations at 22 different sites in iran during the 2004-05 growing season. the experiment was designed as a completely randomized block. the effect of n sources and tim...

objective(s): enzyme immobilization via nanoparticles is perfectly compatible against the other chemical or biological approximate to improve enzyme functions and stability. in this study lactoperoxidase was immobilized onto silica-coated magnetite nanoparticles to improve enzyme properties in the presence of cadmium chloride as an inhibitor. materials and methods:  the process consists of the ...

sio2-coated cobalt ferrite (cofe2o4) nanoparticles were obtained by the hydrolysis of tetraethylorthosilicate in the presence of cofe2o4 nanoparticles in co-precipitation. the effects of sio2coating on the magnetic properties of cofe2o4 nanoparticles were investigated. the structural, morphological and magnetic properties of as-prepared sample were characterization by x-ray diffraction (xrd), f...

In this work, photostability, absorption and emission intensity of coated polycarbonate (PC) sheets with optical brightener (OB) as a wavelength converter material have been investigated. In addition, this coated sheet was used as a wall for microalgae culture flask, as a small scale photobioreactor, for studying the spectral conversion of UV-A radiation to blue light region and its effect ...

This paper investigates homophone naming performance in an individual with impaired word retrieval. The aim of the study is to investigate the status of homophone representations using treatment of homophone picture naming in aphasia. The focus of this paper is the representation of heterographic homophones (words which sound the same but are spelled differently, e.g., 'knight' vs. 'night'). Ad...

The clathrin-coated pit is the major port of entry for many receptors and pathogens and is the paradigm for membrane-based sorting events in higher cells [1]. Recently, it has been possible to reconstitute in vitro the events leading to assembly, invagination, and budding off of clathrin-coated vesicles, allowing dissection of the machinery required for sequestration of receptors into these str...

The process by which clathrin-coated vesicles are produced involves interactions of multifunctional adaptor proteins with the plasma membrane, as well as with clathrin and several accessory proteins and phosphoinositides. Here we review recent findings highlighting new insights into mechanisms underlying clathrin-dependent endocytosis.
