Isolation and Characterization of Strain Exiguobacterium sp. KRL4, a Producer of Bioactive Secondary Metabolites from a Tibetan Glacier

open access: yesMicroorganisms, 2021
Extremophilic microorganisms represent a unique source of novel natural products. Among them, cold adapted bacteria and particularly alpine microorganisms are still underexplored.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Fatty Acid and Amino Acid Profiles of Seven Edible Insects: Focus on Lipid Class Composition and Protein Conversion Factors

open access: yesFoods, 2023
This study is based on the fatty acid and amino acid profiles of seven edible insect species: Acheta domesticus, Alphitobius diaperinus, Blaptica dubia, Galleria mellonella, Locusta migratoria, Tenebrio molitor, and Zophobas morio. The aim of the present

Microbial expression systems for membrane proteins [PDF]

open access: yesMethods, 2018
Despite many high-profile successes, recombinant membrane protein production remains a technical challenge; it is still the case that many fewer membrane protein structures have been published than those of soluble proteins. However, progress is being made because empirical methods have been developed to produce the required quantity and quality of ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Protein metabolism of prolific ewes during late gestation and early lactation [PDF]

open access: yes, 2001
Subject headings: protein / metabolism / ewesIntroduction of prolific crossbred ewes and a new protein evaluation system for ruminants, the DVE/OEB system, necessitate a reconsideration of ewe feeding strategies.

Picky Hsp90-Every Game with Another Mate [PDF]

open access: yes, 2017
In this issue of Molecular Cell, Sahasrabudhe et al. (2017) present a dramatically renovated functional cycle for the molecular chaperone Hsp90, which stimulates re-thinking of the mechanism of this vital protein folding ...

Structural basis for the assembly of the Ragulator-Rag GTPase complex

open access: yesNature Communications, 2017
mTORC1 activity is controlled through Rag GTPases, which are anchored to the lysosome through the Ragulator. Here, the authors give molecular insights into Ragulator-Rag GTPase assembly and present the crystal structures of the Ragulator alone and in ...

Granulated Cane Sugar as a Partial Replacement for Steam-Flaked Corn in Diets for Feedlot Cattle: Ruminal Fermentation and Microbial Protein Synthesis

open access: yesFermentation, 2022
The aim of this study was to evaluate the influence of supplemental granulated cane sugar (GCS) levels (0, 13.3, 26.6, and 39.9% on a dry matter basis) in a steam-flaked corn-based finishing diet on measures of ruminal fermentation and the site and ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS 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 ...
