Discovery and Characterization of a New Cold-Active Protease From an Extremophilic Bacterium via Comparative Genome Analysis and in vitro Expression

Frontiers in Microbiology, 2020
Following a screening of Antarctic glacier forefield-bacteria for novel cold-active enzymes, a psychrophilic strain Psychrobacter sp. 94-6PB was selected for further characterization of enzymatic activities.

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.

Sustainable Upcycling of Fisheries and Aquaculture Wastes Using Fish-Derived Cold-Adapted Proteases

Frontiers in Nutrition, 2022
The fisheries and aquaculture industries are some of the major economic sectors in the world. However, these industries generate significant amounts of wastes that need to be properly managed to avoid serious health and environmental issues.

Differing impact of phosphoglycerate mutase 1-deficiency on brown and white adipose tissue

iScience, 2022
Summary: Brown adipose tissue (BAT) is a metabolically active organ that contributes to the thermogenic response to cold exposure. In addition, other thermogenic cells termed beige adipocytes are generated in white adipose tissue (WAT) by cold exposure ...

Cold‐active microbial enzymes and their biotechnological applications

Microbial Biotechnology
Microorganisms known as psychrophiles/psychrotrophs, which survive in cold climates, constitute majority of the biosphere on Earth. Their capability to produce cold‐active enzymes along with other distinguishing characteristics allows them to survive in ...

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Isolation and characterization of EstC, a new cold-active esterase from Streptomyces coelicolor A3(2). [PDF]

PLoS ONE, 2012
The genome sequence of Streptomyces coelicolor A3(2) contains more than 50 genes coding for putative lipolytic enzymes. Many studies have shown the capacity of this actinomycete to store important reserves of intracellular triacylglycerols in nutrient ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

PRACTICALLY VALUABLE METABOLITES OF MARINE MICROORGANISMS [PDF]

Biotechnologia Acta, 2020
The review considered the modern literature data on the synthesis by fungi, actinobacteria, and bacteria isolated from marine ecosystems (seawater, bottom sediments, flora and fauna, mangrove biomes, glaciers), practically valuable metabolites.
