Structure of l‐rhamnose isomerase in complex with l‐rhamnopyranose demonstrates the sugar‐ring opening mechanism and the role of a substrate sub‐binding site

open access: yesFEBS Open Bio, Volume 3, Issue 1, Page 35-40, January 01, 2013., 2013
l‐Rhamnose isomerase (l‐RhI) catalyzes the reversible isomerization of l‐rhamnose to l‐rhamnulose. Previously determined X‐ray structures of l‐RhI showed a hydride‐shift mechanism for the isomerization of substrates in a linear form, but the mechanism for opening of the sugar‐ring is still unclear.

Overexpression of Transketolase Relieves xylA Repression and Enhances Xylose Utilization in Saccharomyces cerevisiae During Mixed Sugar Fermentation

open access: yesGCB Bioenergy, Volume 17, Issue 7, July 2025.
To overcome the bottleneck of inefficient xylose utilization in lignocellulosic bioethanol production, we constructed a recombinant Saccharomyces cerevisiae strain (INVSc‐xylA‐Xltr1p‐TKL1) by overexpressing the transketolase gene TKL1. This engineering strategy significantly enhanced xylose consumption by 33%, upregulated xylose isomerase (xylA ...

Sugar Alcohols, Caries Incidence, and Remineralization of Caries Lesions: A Literature Review

open access: yesInternational Journal of Dentistry, Volume 2010, Issue 1, 2010., 2010
Remineralization of minor enamel defects is a normal physiological process that is well known to clinicians and researchers in dentistry and oral biology. This process can be facilitated by various dietary and oral hygiene procedures and may also concern dentin caries lesions.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Distribution and phylogenies of enzymes of the Embden‐Meyerhof‐Parnas pathway from archaea and hyperthermophilic bacteria support a gluconeogenic origin of metabolism

open access: yesArchaea, Volume 1, Issue 3, Page 199-221, 2003., 2003
Enzymes of the gluconeogenic/glycolytic pathway (the Embden‐Meyerhof‐Parnas (EMP) pathway), the reductive tricarboxylic acid cycle, the reductive pentose phosphate cycle and the Entner‐Doudoroff pathway are widely distributed and are often considered to be central to the origins of metabolism.

Comprehensive review of sweetpotato flavor compounds: Opportunities for developing consumer‐preferred varieties

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 3, May 2025.
Abstract Flavor contributes significantly to consumer preferences of cooked sweetpotato. Sugars largely drive the sweet taste, while the volatile organic compounds (VOCs), mainly classified as alcohols, aldehydes, ketones, and terpenes, provide characteristic aromas and influence the overall perception of flavor.

GnuR Represses the Expression of Glucose and Gluconate Catabolism in Pseudomonas putida KT2440

open access: yesMicrobial Biotechnology, Volume 17, Issue 11, November 2024.
In this work, we found that both glucose and gluconate can significantly induce the expression of catabolic enzymes of glucose and gluconate metabolism and the four related transcription factors including GnuR in Pseudomonas putida KT2440, a prime chassis for biotechnology.

Efficient Glucose Isomerization to Fructose using Photoregenerable MgSnO3 Catalyst with Cooperative Acid‐Base Sites

open access: yesChemSusChem, Volume 17, Issue 16, August 26, 2024.
A catalyst for the thermal catalytic reaction of glucose isomerization to fructose that can be regenerated through light illumination. Abstract The isomerization of glucose to fructose plays a crucial role in the food industry and the production of biomass‐derived chemicals in biorefineries.
