S-nitrosylation is emerging as a key post-translational protein modification for the transduction of NO as a signaling molecule in plants. This data article supports the research article entitled "Functional and structural changes in plant mitochondrial PrxII F caused by NO" [1]. To identify the Cys residues of the recombinant PrxII F modified after the treatment with S-nitrosylating agents we ...

BACKGROUND The effects and effectiveness of the chaperone pair GroELS on the yield and quality of recombinant polypeptides produced in Escherichia coli are matter of controversy, as the reported activities of this complex are not always consistent and eventually indicate undesired side effects. The divergence in the reported data could be due, at least partially, to different experimental condi...

UNLABELLED We systematically analyzed the capability of the major cytosolic chaperones of Escherichia coli to cope with protein misfolding and aggregation during heat stress in vivo and in cell extracts. Under physiological heat stress conditions, only the DnaK system efficiently prevented the aggregation of thermolabile proteins, a surprisingly high number of 150-200 species, corresponding to ...

The effect of meat cooking on protein aggregation was measured in pig M. Longissimus dorsi. Muscles were aged 4 days in air and then cooked at 100 C for 10 or 30 min. Meat was ground in a KCl solution and the whole extract was delipidated with a mixture of butanol and di-isopropyl ether in a 40:60 v/v ratio. Protein aggregation induced by cooking was evaluated with a laser granulometer, which e...

Neutral atomic sodium and chlorine emissions from cleaved, single-crystal NaCl 100 surfaces due to pulsed, 248-nm excimer laser irradiation have been characterized by time-resolved, quadrupole mass spectroscopy. At laser fluences below the threshold for optical breakdown, the resulting time-of-flight signals are consistent with particles emitted in thermal equilibrium with a laser-heated surfac...

Background & Aims: Alzheimer's disease is a neurodegenerative disorder characterized by the abnormal aggregation of amyloid-β plaques in the brain. Although several studies have been done for finding effective medicines in the treatment of this disease, a drug that inhibits amyloid β aggregation and ameliorates the disorder has not been approved so far. One important therapeutic approach is use...

Monoclonal antibodies are the fastest growing class of biotherapeutics. Ensuring their colloidal and conformational stability in liquid dispersions is crucial for maintaining therapeutic efficacy and economic viability. Sugars are often added to increase the colloidal and thermal stability of protein; however, determining which sugar is the most stabilizing requires time and sample-consuming st...

We investigated the influence of molecular packing on the optical and electrical properties of the liquid crystalline dye 4,7-bis[5-(2-fluoro-4-pentyl-phenyl)-2-thienyl]-2,1,3-benzothiadiazole (FPPTB). FPPTB is crystalline at room temperature, exhibits a nematic phase at temperatures above 149 °C and is in an isotropic melt at temperatures above 230 °C. Solution processed FPPTB films were subje...

Due to their remarkably high structural stability, proteins from extremophiles are particularly useful in numerous biological applications. Their utility as alternative protein scaffolds could be especially valuable in small antibody mimetic engineering. These artificial binding proteins occupy a specific niche between antibodies and low molecular weight substances, paving the way for developme...

Phytochromes (phys) encompass a diverse collection of biliproteins that enable cellular light perception by photoconverting between a red-light-absorbing ground state (Pr) and a far-red light-absorbing active state (Pfr). Based on the central role of plant phys in controlling numerous agriculturally important processes, their rational redesign offers great promise toward accelerating crop impro...
