Isomerase - Wikipedia
WEBGlucose isomerase (also known as xylose isomerase) catalyzes the conversion of D-xylose and D-glucose to D-xylulose and D-fructose. Like most sugar isomerases, glucose isomerase catalyzes the interconversion of aldoses and ketoses. The conversion of glucose to fructose is a key component of high-fructose corn syrup production.
Isomerase | enzyme | Britannica
WEBisomerase, any one of a class of enzymes that catalyze reactions involving a structural rearrangement of a molecule. Alanine racemase, for example, catalyzes the conversion of L-alanine into its isomeric (mirror-image) form, D-alanine. An isomerase called mutarotase catalyzes the conversion of α-d-glucose into β-d-glucose. cf.
Isomerase - an overview | ScienceDirect Topics
WEBIsomerases catalyze isomerization reactions such as racemization and epimerization. They have not been used in many industrial applications. However, one of the most successful enzyme-based biocatalytic processes involves an isomerase: the use of glucose isomerase for the production of high-fructose corn syrup (HFCS).
The evolution of enzyme function in the isomerases - PMC
WEBIsomerases are used in many applications. In metabolic engineering, xylose isomerase (EC 5.3.1.5) has been traditionally used to convert glucose to fructose in the syrup industry and has recently been engineered to increase the …
Glucose Isomerase: Functions, Structures, and Applications
WEBJan 3, 2022 · Glucose isomerase (GI, also known as xylose isomerase) reversibly isomerizes D-glucose and D-xylose to D-fructose and D-xylulose, respectively. GI plays an important role in sugar metabolism, fulfilling nutritional requirements in bacteria.

WEBJul 7, 2021 · Keywords: triosephosphate isomerase, isomerization, quantum refinement, QM/MM, neutron crystallography, refinement, enzyme mechanisms, structural biology. Nearly fifty years ago the triosephosphate isomerase enzyme, from chicken, was first determined by X-ray crystallography (Banner et al., 1975 ). This was achieved via a multiple isomorphous ...
Isomerase - an overview | ScienceDirect Topics
WEBGlucose isomerase is an industrially important enzyme due to its application in the production of high-fructose corn syrup, as well as in the fructose production by isomerization of glucose to fructose, which is applied as an alternative to cane sugar (Bhosale et al., 1996; Olsen, 2002).
Glucose Isomerase | SpringerLink
WEBAbstract. D-Glucose/Xylose isomerase (D-xylose ketol isomerase, EC 5.3.1.5) (GI) occupies a pivotal position with respect to its applications in both physiological and commercial fields. It is one of the three highest tonnage value enzymes, amylase and protease being the other two.
