The molecular basis of the effect of temperature on enzyme activity

open access: yes, 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.

Immobilization of Cold-Active Cellulase from Antarctic Bacterium and Its Use for Kelp Cellulose Ethanol Fermentation

open access: yesBioResources, 2015
Immobilization is an effective way to solve the problem associated with the application of cold-active cellulase in industrial processes. In this study, a cold-active cellulase from the Antarctic psychrophilic bacterium Pseudoalteromonas sp.

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

open access: yes, 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.

Active droplets through enzyme-free, dynamic phosphorylation

open access: yes, 2023
Life continuously transduces energy to perform critical functions using energy stored in reactive molecules like ATP or NADH. ATP dynamically phosphorylates active sites on proteins and thereby regulates their function.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Evolution of substrate specificity in a recipient's enzyme following horizontal gene transfer [PDF]

open access: yes, 2013
Despite the prominent role of horizontal gene transfer (HGT) in shaping bacterial metabolism, little is known about the impact of HGT on the evolution of enzyme function.

Structural and functional characterization of cold-active sialidase isolated from Antarctic fungus Penicillium griseofulvum P29

open access: yesBiochemistry and Biophysics Reports
The fungal strain, Penicillium griseofulvum P29, isolated from a soil sample taken from Terra Nova Bay, Antarctica, was found to be a good producer of sialidase (P29).

Optimizing and purifying extracellular cold- active lipase from Talaromyces pinophilus AUMC 308 for potential use in industrial detergents [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research
In this study, a strain of Talaromyces pinophilus AUMC 308 was used. The 15th days of fermentation at pH 6.0, 15°C with ammonium chloride as the nitrogen source were shown to be the optimal settings for the synthesis of the enzyme.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

MACiE: a database of enzyme reaction mechanisms.

open access: yes, 2005
SUMMARY: MACiE (mechanism, annotation and classification in enzymes) is a publicly available web-based database, held in CMLReact (an XML application), that aims to help our understanding of the evolution of enzyme catalytic mechanisms and also to create
