Molecules, 2019 A novel RNase R, psrnr, was cloned from the Antarctic bacterium Psychrobacter sp. ANT206 and expressed in Escherichia coli (E. coli). A bioinformatics analysis of the psrnr gene revealed that it contained an open reading frame of 2313 bp and encoded a ...

Purification and characterization of a novel cold adapted fungal glucoamylase
Microbial Cell Factories, 2017 Background Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature.

Microbial Cell Factories, 2011 Background Cold-adapted enzymes are proteins produced by psychrophilic organisms that display a high catalytic efficiency at extremely low temperatures. Chitin consists of the insoluble homopolysaccharide β-(1, 4)-linked N-acetylglucosamine, which is the

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

NMR solution structure of a cold-adapted thiol-disulfide oxidoreductase [PDF]
, 2011 Psychrophilic enzymes produced by cold-adapted micro-organisms have successfully overcome the low temperature challenge and adapted to maintain high catalytic rates in their permanently cold environments.

Ferrets exclusively synthesize Neu5Ac and express naturally humanized influenza A virus receptors [PDF]
, 2014 Mammals express the sialic acids N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc) on cell surfaces, where they act as receptors for pathogens, including influenza A virus (IAV). Neu5Gc is synthesized from Neu5Ac by the enzyme

Fundamentals of Cold-Adapted Enzymes
, 2008 The authors wish to thank N. Gerardin, A. Dernier and R. Marchand for their skilful technical assistance and the French Institute for Polar Research (IPEV – Institut Polaire Francais) for generously accommodating our research fellows at the French Antarctic station J.S. Dumont d’Urville in Terre Adelie.

FEBS 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 ...

Metabolic and Stress Responses in Senegalese Soles (Solea senegalensis Kaup) Fed Tryptophan Supplements: E ects of Concentration and Feeding Period [PDF]
, 2019 The objective of this study was to assess the impact of di erent dietary Trp concentrations on the stress and metabolism response of juvenile Senegalese soles (Solea senegalensis). Fish (38.1 1.9 g) were fed di erent Trp-enriched feeds (0%, 1% and 2%
