Structural analysis and functional evaluation of the disordered ß-hexosyltransferase region from <i>Hamamotoa (Sporobolomyces) singularis</i>
FRONTIERS IN BIOENGINEERING AND BIOTECHNOLOGY, 11.
author keywords: disorder; expression; kinetics; mutagenesis; transglycosylation; Hamamotoa singularis
TL;DR:
Functional analysis of each glycosylation site found within the C-terminal domain revealed reduced total secreted protein activity, indicating that glycosylation at all four locations is required by the host for the secretion of active enzyme and independent of the removed disordered N-terminal region.

Safety and Modulatory Effects of Humanized Galacto-Oligosaccharides on the Gut Microbiome
FRONTIERS IN NUTRITION, 8.
author keywords: galactooligosaccharide (GOS); N-Acetyl-D-lactosamine (LacNAc); safety; human milk oligosaccharides (HMOs); LacNAc synthesis; mouse models
TL;DR:
The study demonstrated the biological synthesis of hGOS, and signaled its safety and ability to modulate the gut microbiome in vivo, promoting the growth of beneficial microorganisms, including Bifidobacterium and Akkermansia.

The pleiotropic effects of prebiotic galacto-oligosaccharides on the aging gut
MICROBIOME, 9(1).
author keywords: Gut microbiome; Prebiotics; Bifidobacterium; Intestinal permeability; Host-microbiota interactions; Diet; Antibiotics; Metagenomics; Transcriptomics; Organoids
MeSH headings : Aging / drug effects; Aging / genetics; Aging / physiology; Animals; Female; Gastrointestinal Microbiome / drug effects; Intestines / drug effects; Intestines / microbiology; Intestines / physiology; Mice; Mice, Inbred C57BL; Oligosaccharides / pharmacology; Phosphatidylinositol 3-Kinases / metabolism; Prebiotics; Proto-Oncogene Proteins c-akt / metabolism
TL;DR:
Stools from mice exhibiting variable bifidogenic response to GOS injected into colon organoids in the presence of prebiotics reproduced the response and non-response phenotypes observed in vivo suggesting that the composition and functionality of the microbiota are the main contributors to the phenotype.

A novel N-terminal region of the membrane beta-hexosyltransferase: its role in secretion of soluble protein by Pichia pastoris
MICROBIOLOGY-SGM, 162(1), 23–34.
Contributors: n & J. Bruno-Bárcena n
MeSH headings : Amino Acid Motifs; Amino Acid Sequence; Cell Membrane / chemistry; Cell Membrane / enzymology; Cell Membrane / genetics; Fungal Proteins / chemistry; Fungal Proteins / genetics; Fungal Proteins / metabolism; Gene Expression; Hexosyltransferases / chemistry; Hexosyltransferases / genetics; Hexosyltransferases / metabolism; Kinetics; Molecular Sequence Data; Pichia / genetics; Pichia / metabolism; Protein Transport; Yeasts / chemistry; Yeasts / enzymology; Yeasts / genetics
TL;DR:
Lead interference was demonstrated when MFα preceded the putative classical rBHT(1-22) leader, explaining the limited secretion of soluble protein by P. pastoris strains carrying combinations of the predicted structural domains.

Meta-Analysis and Functional Validation of Nutritional Requirements of Solventogenic Clostridia Growing under Butanol Stress Conditions and Coutilization of D-Glucose and D-Xylose
APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 77(13), 4473–4485.
Contributors: H. Heluane n, M. Dagher n & J. Bruno-Bárcena n
MeSH headings : Biofuels; Biotechnology / methods; Butanols / toxicity; Clostridium beijerinckii / drug effects; Clostridium beijerinckii / growth & development; Clostridium beijerinckii / metabolism; Culture Media / chemistry; Fermentation; Gene Expression Profiling; Gene Expression Regulation, Bacterial; Glucose / metabolism; Stress, Physiological; Xylose / metabolism
TL;DR:
Results indicated that C. beijerinckii SA-1 was able to coferment hexose/pentose sugar mixtures in the absence of a glucose repression effect, and the analysis suggests that the solvent and acid resistance mechanisms found in this strain are differentially regulated compared to strain NRRL B-527.
