N-terminal Fusion of a Hyperthermophilic Chitin-Binding Domain to Xylose Isomerase from Thermotoga neapolitana Enhances Kinetics and Thermostability of Both Free and Immobilized Enzymes
BIOTECHNOLOGY PROGRESS, 26(4), 993–1000.
author keywords: xylose isomerase; hyperthermophile; Thermotoga neapolitana; chitin-binding domain
MeSH headings : Aldose-Ketose Isomerases / genetics; Aldose-Ketose Isomerases / metabolism; Chitin / metabolism; Enzyme Stability; Enzymes, Immobilized / genetics; Enzymes, Immobilized / metabolism; Kinetics; Protein Binding; Protein Structure, Tertiary / genetics; Protein Structure, Tertiary / physiology; Recombinant Proteins / genetics; Recombinant Proteins / metabolism; Thermotoga neapolitana / enzymology
TL;DR:
Molecular modeling results suggest that the N‐terminal fusion impacted subunit interactions, thereby contributing to the enhanced thermostability of both the unbound and immobilized CBD‐TNXI, and played a role in modifying active site structure.

2007 journal article
Probing the stability of native and activated forms of alpha(2)-macroglobulin
INTERNATIONAL JOURNAL OF BIOLOGICAL MACROMOLECULES, 42(1), 62–67.
author keywords: alpha M-2; alpha(2)-macroglobulin; alpha(2)-macroglobulin and proteinase incorporation; alpha(2)-macroglobulin and norproteolytic incorporation of lysozyme; alpha(2)-macroglobulin stabilization
MeSH headings : Amino Acid Sequence; Animals; Hot Temperature; Humans; Ligands; Molecular Sequence Data; Peptide Hydrolases / chemistry; Protein Conformation; Transition Temperature; alpha-Macroglobulins / chemistry
TL;DR:
Differential scanning calorimetry and urea gel electrophoresis demonstrate that both bait region cleavage and covalent incorporation of protein ligands in the thioester pocket play critical roles in the stability of α 2 M complexes.

Role of the beta 1 subunit in the function and stability of the 20S proteasome in the hyperthermophilic archaeon Pyrococcus furiosus
JOURNAL OF BACTERIOLOGY, 189(2), 583–590.
MeSH headings : Archaeal Proteins / genetics; Archaeal Proteins / metabolism; Archaeal Proteins / physiology; Calorimetry, Differential Scanning; Genome, Archaeal; Hot Temperature; Molecular Chaperones / genetics; Molecular Chaperones / metabolism; Proteasome Endopeptidase Complex / genetics; Proteasome Endopeptidase Complex / metabolism; Proteasome Endopeptidase Complex / physiology; Protein Subunits / genetics; Protein Subunits / metabolism; Protein Subunits / physiology; Pyrococcus furiosus / genetics; Pyrococcus furiosus / metabolism; Temperature; Transcription, Genetic
TL;DR:
Results indicate that the β1 subunit in the P. furiosus 20S proteasome plays a thermostabilizing role and influences biocatalytic properties, suggesting that β subunit composition is a factor in archaeal proteasom function during thermal stress, when polypeptide turnover is essential to cell survival.

Denaturation and aggregation of three alpha-lactalbumin preparations at neutral pH
JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, 53(8), 3182–3190.
author keywords: alpha-lactalbumin; whey proteins; denaturation and aggregation
MeSH headings : Calorimetry, Differential Scanning; Chemical Phenomena; Chemistry, Physical; Dimerization; Electrophoresis, Polyacrylamide Gel; Hot Temperature; Hydrogen-Ion Concentration; Lactalbumin / chemistry; Nephelometry and Turbidimetry; Protein Denaturation
TL;DR:
The denaturation and aggregation of reagent-grade, ion-exchange chromatography purified, and a commercial-grade alpha-lactalbumin were studied and the interrelationship between specific electrostatic interactions and hydrophobic attraction, in relation to the formation of disulfide-bonded products, is discussed.

Influence of divalent cations on the structural thermostability and thermal inactivation kinetics of class II xylose isomerases
FEBS JOURNAL, 272(6), 1454–1464.
author keywords: inactivation kinetics; metal cofactors; thermostability; xylose isomerases
MeSH headings : Aldose-Ketose Isomerases / antagonists & inhibitors; Aldose-Ketose Isomerases / chemistry; Aldose-Ketose Isomerases / metabolism; Bacillus / enzymology; Bacterial Proteins / antagonists & inhibitors; Bacterial Proteins / chemistry; Bacterial Proteins / metabolism; Cations, Divalent / pharmacology; Cobalt / pharmacology; Enzyme Stability; Escherichia coli / enzymology; Kinetics; Magnesium / pharmacology; Manganese / pharmacology; Protein Denaturation; Recombinant Proteins / antagonists & inhibitors; Recombinant Proteins / chemistry; Recombinant Proteins / metabolism; Thermodynamics; Thermotoga maritima / enzymology
TL;DR:
The results reported here suggest that, unlike the other class II XIs examined, single metals are required for TNXI activity, but are not essential for its structural thermostability.

Glucose-to-fructose conversion at high temperatures with xylose (glucose) isomerases from Streptomyces murinus and two hyperthermophilic Thermotoga species
BIOTECHNOLOGY AND BIOENGINEERING, 80(2), 185–194.
author keywords: Thermotoga; xylose isomerase; Streptomyces murinus; hyperthermophile
MeSH headings : Aldose-Ketose Isomerases / chemistry; Aldose-Ketose Isomerases / classification; Aldose-Ketose Isomerases / metabolism; Bioreactors; Enzyme Activation; Enzymes, Immobilized / metabolism; Fructose / biosynthesis; Glucose / metabolism; Gram-Negative Anaerobic Straight, Curved, and Helical Rods / classification; Gram-Negative Anaerobic Straight, Curved, and Helical Rods / enzymology; Gram-Negative Anaerobic Straight, Curved, and Helical Rods / metabolism; Hot Temperature; Hydrogen-Ion Concentration; Sensitivity and Specificity; Species Specificity; Streptomyces / classification; Streptomyces / enzymology; Thermotoga maritima / classification; Thermotoga maritima / enzymology
TL;DR:
In the presence of both cations, these enzymes showed the potential to catalyze glucose-to-fructose conversion at 80 degrees C with estimated lifetime productivities on the order of 2000 kg fructose per kilogram enzyme, a value competitive with enzymes currently used at 55 degrees to 65 degrees C, but with the additional advantage of higher fructose concentrations.
