Discovery of a cryptic aminoacidic triad involved in the temperature adaptation of GH1 enzymes. [PDF]
FEBS JCold‐active enzymes retain high catalytic activity at low temperatures but are characterized by thermal instability, a behavior not fully understood. Comparison between a cold‐active GH1 and its mesophilic counterparts highlights the role of a three‐residue motif (W‐M‐F) in conferring structural stability to a mesophilic GH1.

Activation parameters, enthalpy-entropy compensation and the temperature-dependent activity of enzymes. [PDF]
Protein SciAbstract The increase in enzyme‐catalyzed reaction rates with temperature is typically modeled using Arrhenius or Eyring relations. Interpretation of extracted parameters is subject to multiple caveats. Here we analyze the impact of temperature variations of underlying activation or Eyring parameters and of temperature‐dependent contributions to ...

The Sensory, Chemical and Microbiological Quality of Sous-Vide Cooked Sea Bass (<i>Dicentrarchus labrax</i> Linneaus, 1758) With Liquid Smoke Flavor. [PDF]
Food Sci NutrThe processing of sea bass fillets, flavored with liquid smoke‐salt‐vegetable oil, using sous‐vide technology is an innovative method that both enhances organoleptic quality and ensures safe preservation. The fillets, which were flavored and vacuum‐sealed, were cooked at different temperatures and then transferred to cold storage following rapid ...

Molecular characterization of cold adaptation of membrane proteins in the Vibrionaceae core-genome. [PDF]
PLoS ONE, 2012 Cold-adaptation strategies have been studied in multiple psychrophilic organisms, especially for psychrophilic enzymes. Decreased enzyme activity caused by low temperatures as well as a higher viscosity of the aqueous environment require certain ...

Structure analysis of a new psychrophilic marine protease. [PDF]
PLoS ONE, 2011 A new psychrophilic marine protease was found from a marine bacterium Flavobacterium YS-80 in the Chinese Yellow Sea. The protease is about 49 kD with an isoelectric point about 4.5.
