Thermal denaturation and renaturation of γ-glutamyltranspeptidase of Escherichia coli.
نویسندگان
چکیده
Heat-treated γ-glutamyltranspeptidase of Escherichia coli recovered enzymatic activity after incubation at 4 °C, while heat-treated γ-glutamyltranspeptidase of Bacillus subtilis did not. Fluorescent spectra, CD spectra, and native polyacrylamide gel electrophoresis analysis suggested that the dimer of E. coli γ-glutamyltranspeptidase was separated into protomers by heat-treatment, but was renatured by incubation at 4 °C.

Stable transformation of an Arabidopsis cell suspension culture with firefly luciferase providing a cellular system for analysis of chaperone activity in vivo.
Using Agrobacterium, we developed a method to transform an Arabidopsis cell suspension culture. A stably transformed cell line expressing high levels of firefly luciferase (Luc) was used for in vivo studies of thermal denaturation and renaturation of the enzyme and the protective role of different chaperones. Luc activity was monitored under heat stress and recovery conditions in control, therm...
متن کاملIntermediates on the reassociation pathway of phosphofructokinase I from Escherichia coli.
The folding and association pathway of the allosteric phosphofructokinase from Escherichia coli has been investigated after complete denaturation of the protein in guanidine hydrochloride by spectroscopical methods, fluorescence and circular dichroism. Three successive processes can be observed during the renaturation of this protein. First, a fast reaction, detected by fluorescence, results in...
متن کاملUV Melting of G-Quadruplexes.
Absorbance versus temperature curves can provide information on the thermal stability of DNA or RNA quadruplexes. Quadruplex denaturation or renaturation can be followed by recording absorbance at 295 nm rather than 260 nm, the wavelength used to monitor duplex denaturation. This unit describes the use of absorbance versus temperature curves to determine melting temperatures (T(m) values) and m...

Background: The radiation emitted from electromagnetic fields (EMF) can cause biological effects on prokaryotic and eukaryotic cells, including non-thermal effects. Objective: The present study evaluated the non-thermal effects of wireless fidelity (Wi-Fi) operating at 2.4 GHz part of non-ionizing EMF on different pathogenic bacterial strains (Escherichia coli 0157H7, Staphylococcus aureu...
متن کاملChaperone properties of Escherichia coli thioredoxin and thioredoxin reductase.
Thioredoxin, thioredoxin reductase and NADPH form the thioredoxin system and are the major cellular protein disulphide reductase. We report here that Escherichia coli thioredoxin and thioredoxin reductase interact with unfolded and denatured proteins, in a manner similar to that of molecular chaperones that are involved in protein folding and protein renaturation after stress. Thioredoxin and/o...
