Aldose-ketose isomeraseIsomerizationD-Mannose isomerase (MI) reversibly isomerizes D-mannose to D-fructose, and is attractive for producing D-mannose from inexpensive D-fructose. It belongs to the N-acylglucosamine 2-epimerase (AGE) superfamily along with AGE, cellobiose 2-epimerase (CE), and ...

Both proteins were found to show no AGE activity but showed cofactor-independent aldose–ketose isomerase activity involved in the interconversion of monosaccharides, mannose, fructose, and glucose, or lyxose and xylulose. In order to clarify the structure/function relationship of YihS, we determined ...
D-Mannose is an epimer of glucose at the C-2 position and exists in nature as a component of mannan. It has 60 and 86% sweetness than that of sucrose and D-glucose, respectively. Because of its low-calorie and nontoxic features, D-mannose is used widely in food, medicine, cosmetic, ...
D-AI can catalyze the isomerization of D-arabinose (aldose) to D-ribulose (ketose) [26]. The same enzyme also catalyzed L-fucose to L-fuculose. In E. coli, this enzyme metabolized L-fucose and named L-FI [103]. Isomerization of D-arabinose to D-ribulose, L-fucose to L-fuculose,...
ketose 3-epimerases, polyol dehydrogenases, and aldose isomerases. Recently, more attention has been paid on the Izumoring of hexoses, especially the D-zone hexoses. So far, at least ten isomerases have been used for the isomerization reactions between D-aldohexoses and D-ketohexoses. In this...
Isotopic exchange plus substrate and inhibition kinetics of D-xylose isomerase do not support a proton-transfer mechanism. The D-xylose isomerase of Streptomyces olivochromogenes is a Mg2+- or Mn(2+)-dependent enzyme that catalyzes the aldose-ketose isomerization of xylose to x... KN Allen,A ...
An L-ribose isomerase which isomerizes aldoses such as L-ribose, D-lyxose, D-talose, D-mannose, L-allose and L-gulose into their corresponding ketoses such as L-ribulose, D-xylulose, D-tagatose, D-fructose, L-psicose and L-sorbose. The e... K Izumori,K Tsusaki - US 被引量...
YihS enzyme is a kind of aldose-ketose isomerase that catalyzes interconversion betweend-glucose andd-fructose;d-fructose andd-mannose; andd-lyxose andd-xylulose. To further determine the categorization ofP. geniculataAGEase, the kinetics for different substrates were investigated (Table 3).P. geni...
