Abstract:
Near-infrared fluorescent proteins (NIR FPs) based on the complexes of bacterial phytochromes with their natural biliverdin chromophore are widely used as genetically encoded optical probes for visualization of cellular processes and deep-tissue imaging of cells and organs in living animals. In this work, we show that the steady-state and kinetic dependencies of the various spectral characteristics of iRFP713, developed from the bacterial phytochrome RpBphP2 and recorded at protein unfolding induced by guanidine hydrochloride (GdnHCl), guanidine thiocyanate (GTC), and urea, differ substantiall

Abstract:
ABSTRACT NAD-dependent glutamate dehydrogenase (l-glutamate:NAD oxidoreductase, deaminating; EC 1.4.1.2 ) was purified to homogeneity from a crude extract of the continental hyperthermophilic archaeonPyrobaculum islandicum by two successive Red Sepharose CL-4B affinity chromatographies. The enzyme is the most thermostable NAD-dependent dehydrogenase found to date; the activity was not lost after incubation at 100°C for 2 h. The enzyme activity increased linearly with temperature, and the maximum was observed at ca. 90°C. The enzyme has a molecular mass of about 220 kDa and consists of six subu

Abstract:
Maintenance of native structure and function of the protein is a major concern for industrial production of aggregation prone therapeutically important recombinant proteins. Aggregation may results due to change in the native conformation of proteins under different stress conditions. To overcome the problem of protein aggregation, role of silver and gold nanoparticles have been investigated. The nanoparticles owing to their affirmative interaction with the proteins possess chaperoning activities and protect the native state from denaturation. In the present study, through performing chemical

Abstract:
Bovine pancreatic PLA2 (phospholipase A2) is a 14 kDa protein whose structure is highly cross-linked by seven disulphide bonds. We investigated the structural stability of this enzyme by the method of ‘disulphide-scrambling’ with denaturants such as urea, GdmCl (guanidine hydrochloride), GdmSCN (guanidine thiocyanate) and at high temperatures in the presence of 2-mercaptoethanol (0.2 mM) as thiol initiator. Reverse-phase HPLC was used to follow denaturation. To denature 50% of the native protein, 1.25 M GdmSCN, approx. 3 M GdmCl and higher than 8 M urea were required. Only 20% of the protein w

Abstract:
It has been reported that the activation of dihydrofolate reductase (DHFR) from L1210 mouse leukaemia cells by KCl or thiol modifiers is accompanied by increased digestibility by proteinases [Duffy, Beckman, Peterson, Vitols and Huennekens (1987) J. Biol. Chem. 262, 7028–7033], suggesting a loosening up of the general compact structure of the enzyme. In the present study, the peptide fragments liberated from the chicken liver enzyme by digestion with trypsin in dilute solutions of urea or guanidine hydrochloride (GuHCl) have been separated by FPLC and sequenced. The sequences obtained are uniq

Abstract:
The lactic acid induced unfolding and the salt-induced folding of creatine kinase (CK) were studied by enzyme activity, fluorescence emission spectra, circular dichroism spectra, and native polyacrylamide gel electrophoresis. The results showed that the kinetics of CK inactivation was a monophase process. Lactic acid caused inactivation and unfolding of CK with no aggregation during CK denaturation. The unfolding of the whole molecule and the inactivation of CK in solutions of different concentration of lactic acid were compared. Much lower lactic acid concentration values were required to bri
