Psychrophilic enzymes: strategies for cold-adaptation [PDF]
Essays in Biochemistry, 2023 Abstract Psychrophilic organisms thriving at near-zero temperatures synthesize cold-adapted enzymes to sustain cell metabolism. These enzymes have overcome the reduced molecular kinetic energy and increased viscosity inherent to their environment and maintained high catalytic rates by development of a diverse range of structural ...

Exercise performance in acute and chronic cold exposure
Journal of Physical Fitness and Sports Medicine, 2015 This review focuses on the suppression of physical performance in a cold environment and the underlying physiological mechanisms. There are many situations where humans have to perform physical activities in a cold environment.

Ecological Indicators, 2021 Soil water retention capacity is an essential component of the land surface processes and hydrological cycles. Although the effect of grassland degradation on soil water retention capacity have been well documented, few studies have focused on how soil ...

Industrial Health, 2009 Nowdays, occupational and recreational activities in cold environments are common. Exposure to cold induces thermoregulatory responses like changes of behaviour and physiological adjustments to maintain thermal balance either by increasing metabolic heat production by shivering and/or by decreasing heat losses consecutive to peripheral cutaneous ...

Metabolic Robustness to Growth Temperature of a Cold- Adapted Marine Bacterium
mSystems, 2023 Microbial communities experience continuous environmental changes, with temperature fluctuations being the most impacting. This is particularly important considering the ongoing global warming but also in the “simpler” context of seasonal variability of ...

Enzymes from Marine Polar Regions and Their Biotechnological Applications
Marine Drugs, 2019 The microorganisms that evolved at low temperatures express cold-adapted enzymes endowed with unique catalytic properties in comparison to their mesophilic homologues, i.e., higher catalytic efficiency, improved flexibility, and lower thermal stability ...

Molecular basis of cold adaptation [PDF]
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2002 Cold–adapted, or psychrophilic, organisms are able to thrive at low temperatures in permanently cold environments, which in fact characterize the greatest proportion of our planet. Psychrophiles include both prokaryotic and eukaryotic organisms and thus represent a significant proportion of the living world. These organisms produce cold–evolved enzymes

Novel Cold-Adapted Esterase MHlip from an Antarctic Soil Metagenome
Biology, 2013 An Antarctic soil metagenomic library was screened for lipolytic enzymes and allowed for the isolation of a new cytosolic esterase from the a/b hydrolase family 6, named MHlip. This enzyme is related to hypothetical genes coding esterases, aryl-esterases
