Engineering of Thermal Stability in a Cold-Active Oligo-1,6-Glucosidase from Exiguobacterium sibiricum with Unusual Amino Acid Content

Biomolecules, 2021
A gene coding for a novel putative amylase, oligo-1,6-glucosidase from a psychrotrophic bacterium Exiguobacterium sibiricum from Siberian permafrost soil was cloned and expressed in Escherichia coli. The amino acid sequence of the predicted protein EsOgl

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

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.

Methane-carbon flow into the benthic food web at cold seeps – a case study from the Costa Rica subduction zone [PDF]

, 2013
Cold seep ecosystems can support enormous biomasses of free-living and symbiotic chemoautotrophic organisms that get their energy from the oxidation of methane or sulfide.

Engineering the properties of a cold active enzyme through rational redesign of the active site [PDF]

European Journal of Biochemistry, 2001
In an effort to explore the effects of local flexibility on the cold adaptation of enzymes, we designed point mutations aiming to modify side‐chain flexibility at the active site of the psychrophilic alkaline phosphatase from the Antarctic strain TAB5.
