Astroenzymology – the environmental limits of enzyme activity [PDF]

, 2003
Using organisms from extreme terrestrial environments as models for extraterrestrial life may lead us to underestimate the range of environments that life may inhabit.

Endolysins from Antarctic Pseudomonas Display Lysozyme Activity at Low Temperature

Marine Drugs, 2020
Organisms specialized to thrive in cold environments (so-called psychrophiles) produce enzymes with the remarkable ability to catalyze chemical reactions at low temperature.

Characterization of a novel cold-adapted intracellular serine protease from the extremophile Planococcus halocryophilus Or1

Frontiers in Microbiology, 2023
The enzymes of microorganisms that live in cold environments must be able to function at ambient temperatures. Cold-adapted enzymes generally have less ordered structures that convey a higher catalytic rate, but at the cost of lower thermodynamic ...

The molecular basis of the effect of temperature on enzyme activity [PDF]

, 2010
Experimental data show that the effect of temperature on enzymes cannot be adequately explained in terms of a two-state model based on increases in activity and denaturation.

Effects of chronic cold treatment on root elongation and gene expression in "Arabidopsis thaliana" [PDF]

, 2008
Low temperature is a major limitation of plant growth. Cold adaptation is important for the survival and distribution of plant species at high elevations and high latitudes.

Psychrophilic Enzymes: From Folding to Function and Biotechnology

Scientifica, 2013
Psychrophiles thriving permanently at near-zero temperatures synthesize cold-active enzymes to sustain their cell cycle. Genome sequences, proteomic, and transcriptomic studies suggest various adaptive features to maintain adequate translation and proper

Psychrophiles: Ecological significance and potential industrial application

South African Journal of Science, 2018
The bulk of earth’s biosphere is cold (5 °C) that sustains a broad diversity of microbial life by triggering physiological response(s) to ensure survival in cold and frozen ecosystems.

Isolation and characterization of a new cold-active protease from psychrotrophic bacteria of Western Himalayan glacial soil

Scientific Reports, 2021
As an approach to the exploration of cold-active enzymes, in this study, we isolated a cold-active protease produced by psychrotrophic bacteria from glacial soils of Thajwas Glacier, Himalayas.
