Tin-containing zeolites are highly active catalysts for the isomerization of glucose in water [PDF]

, 2010
The isomerization of glucose into fructose is a large-scale reaction for the production of high-fructose corn syrup (HFCS; reaction performed by enzyme catalysts) and recently is being considered as an intermediate step in the possible route of biomass ...

Structural Insights into the Epimerization of β-1,4-Linked Oligosaccharides Catalyzed by Cellobiose 2-Epimerase, the Sole Enzyme Epimerizing Non-anomeric Hydroxyl Groups of Unmodified Sugars [PDF]

, 2013
Cellobiose 2-epimerase (CE) reversibly converts d-glucose residues into d-mannose residues at the reducing end of unmodified β1,4-linked oligosaccharides, including β-1,4-mannobiose, cellobiose, and lactose.

Sn-Beta zeolites with borate salts catalyse the epimerization of carbohydrates via an intramolecular carbon shift [PDF]

, 2012
Carbohydrate epimerization is an essential technology for the widespread production of rare sugars. In contrast to other enzymes, most epimerases are only active on sugars substituted with phosphate or nucleotide groups, thus drastically restricting ...

Safety evaluation of the food enzyme xylose isomerase from the genetically modified Streptomyces rubiginosus strain DP‐Pzn37

EFSA Journal, Volume 18, Issue 1, January 2020., 2020
Abstract The food enzyme is a d‐xylose aldose‐ketose‐isomerase (EC 5.3.1.5) produced with the genetically modified Streptomyces rubiginosus strain DP‐Pzn37 by Danisco US Inc. Although the production strain contains antibiotic resistance genes, the food enzyme was shown to be free from viable cells of the production organism and its DNA. The food enzyme

ITRAQ‐Based Quantitative Proteomics Reveals the Proteome Profiles of Primary Duck Embryo Fibroblast Cells Infected with Duck Tembusu Virus

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Outbreaks of duck Tembusu virus (DTMUV) have caused substantial economic losses in the major duck‐producing regions of China since 2010. To improve our understanding of the host cellular responses to virus infection and the pathogenesis of DTMUV infection, we applied isobaric tags for relative and absolute quantification (iTRAQ) labeling coupled with ...

Safety evaluation of the food enzyme glucose isomerase from Streptomyces murinus (strain NZYM‐GA)

EFSA Journal, Volume 17, Issue 1, January 2019., 2019
Abstract The food enzyme is a glucose isomerase (d‐xylose aldose‐ketose‐isomerase; EC 5.3.1.5) produced with a non‐genetically modified Streptomyces murinus strain NZYM‐GA by Novozymes A/S. The glucose isomerase is intended only to be used in an immobilised form in glucose isomerisation for the production of high fructose syrups.

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

FEBS 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.
