Catalytic role of the calcium ion in GH97 inverting glycoside hydrolase [PDF]

, 2014
The role of calcium ion in the active site of the inverting glycoside hydrolase family 97 enzyme, BtGH97a, was investigated through structural and kinetic studies. The calcium ion was likely directly involved in the catalytic reaction.

Functional metagenomics identifies an exosialidase with an inverting catalytic mechanism that defines a new glycoside hydrolase family (GH156)

Journal of Biological Chemistry, 2018
Exosialidases are glycoside hydrolases that remove a single terminal sialic acid residue from oligosaccharides. They are widely distributed in biology, having been found in prokaryotes, eukaryotes, and certain viruses.

Synthetic Biology‐Based Engineering Living Therapeutics for Antimicrobial Application

Exploration, EarlyView.
This perspective highlights synthetic biology‐driven antibacterial strategies, focusing on three innovative approaches: engineered bacteriophages for precision bacterial targeting, reprogrammed microbes that detect quorum‐sensing signals or metabolites to release antimicrobials, and engineering mammalian cells that recognize pathogen‐associated ...

4,3-α-Glucanotransferase, a novel reaction specificity in glycoside hydrolase family 70 and clan GH-H

Scientific Reports, 2017
Lactic acid bacteria possess a diversity of glucansucrase (GS) enzymes that belong to glycoside hydrolase family 70 (GH70) and convert sucrose into α-glucan polysaccharides with (α1 → 2)-, (α1 → 3)-, (α1 → 4)- and/or (α1 → 6)-glycosidic bonds.

Bioactive Polysaccharides Targeting Gut Microbiota to Modulate Host Health: A Gear Effect Theory

Food Frontiers, EarlyView.
The “Gear Effect” mechanism of bioactive polysaccharides driving gut microbiota to modulate host health. ABSTRACT Bioactive polysaccharides are macromolecular polymers with broad biological activities. Recent evidence has highlighted their role in modulating host health primarily through interactions with gut microbiota.

Polysaccharide conformations measured by solution state x-ray scattering [PDF]

, 2019
Polysaccharides are semi-flexible polymers composed of sugar residues with a myriad of important functions including structural support, energy storage and immunogenicity. The local conformation of such chains is a crucial factor governing their interactions, where the relative orientation of adjacent sugar rings determines the propensity for hydrogen ...

In vitro micropropagation and apocarotenoid gene expression in saffron [PDF]

arXiv, 2022
Saffron (Crocus sativus L.) is a triploid, sterile, monocot plant belonging to the family Iridaceae, sub-family Crocoideae. C.sativus only blooms once a year and should be collected within a very short duration, the stigmas of Saffron flowers are harvested manually and subjected to desiccation then have been used as a spice.

Native synthetic microbial communities enhance zha‐chili by boosting the fermentation capacity of indigenous microorganisms

iMetaOmics, EarlyView.
Traditional fermented foods in synthetic microbial communities (SynComs). We simulated the production of zha‐chili, a traditional fermented food, in the laboratory, intending to address the following questions: How are SynComs constructed, and what is the effect of inoculation with SynComs on the quality of zha‐chilli? How does inoculation with SynComs
