Mechanism of thermoinactivation of immobilized glucose isomerase

Biotechnology and Bioengineering, 1989
AbstractIrreversible thermoinactivation of immobilized glucose isomerase from Streptomyces olivochromogenes has been mechanistically investigated at the pH‐optimum of enzymatic activity (pH 8.0). Ligands (high fructose corn syrup and the competitive inhibitor xylitol) greatly stabilize the immobilized enzyme at high temperatures.

Electrophoretic characterization of amebal glucose phosphate isomerases

Experimental Parasitology, 1968
Abstract An electrophoretic method for the characterization of glucose phosphate isomerase has been developed. This method was applied to the enzyme from 18 different cultures of amebae. Five strains of atypical Entamoeba histolytica and two strains of E. moshkowskii yielded a fast-migrating isomerase. Two strains of E.

Immunoaffinity purification of glucose/xylose isomerase fromStreptomyces

Applied Biochemistry and Biotechnology, 1991
A procedure was developed to purify glucose/xylose isomerase from cell extract of Streptomyces sp. NCIM 2730 using immunoaffinity chromatography. High-titer polyclonal antibodies were raised in rabbit using electrophoretically homogeneous glucose/xylose isomerase as an antigen.

A New Regenerable Immobilized Glucose Isomerase

Starch - Stärke, 1986
AbstractA new, immobilized glucose isomerase high productivity has been developed for isomerization of glucose into high fructose syrups. Soluble glucose isomerase fromStreptomyces rubiginosusis highly purified and electrostatically adsorbed onto a granular DEAE‐cellulose comprised of fibrous DEAE‐cellulose, food grade polystyrene and titania. The same

Kinetic Roughening of Glucose Isomerase Crystals

Crystal Growth & Design, 2008
Protein crystals grow by the incorporation of growth units from solution into the crystal bulk. At low supersaturation, growth sites are kinks at step edges that are generated through the formation of spiral dislocations and/or two-dimensional (2D) nucleation.

Sweetzyme — A New Immobilized Glucose Isomerase

Starch - Stärke, 1975
AbstractThe enzymatic isomerization of glucose to fructose is attracting significant attention from scientific as well as industrial quarters. In recent years, high fructose syrups (“isosyrups”) produced by enzymatic isomerization of high DE‐syrups have been introduced successfully, primarily in the U.S.A.A decisive factor for the ability of isosyrups ...

Immobilization of glucose isomerase to cellulose

AIChE Journal, 1978
AbstractGlucose isomerase was covalently bonded to Solka‐floc and DEAE cellulose by several techniques. The best results were obtained with techniques that opened the crystalline structure of the cellulose and kept it that way during immobilization.

Glucose isomerase immobolized on porous glass

Biotechnology and Bioengineering, 1976
AbstractPartially purified glucose isomerase from a Streptomyces species was immobilized on porous glass particles and studied for various characteristics concerning its use as an industrial catalyst. The activities were investigated in relation to the reaction parameters and the enzyme deactivation was studied systematically under various reaction ...

Priapism Caused by Glucose Phosphate Isomerase Deficiency

Journal of Urology, 1976
A case of congenital non-spherocytic hemolytic anemia of unknown etiology is described. The patient had priapism and further hematologic evaluation revealed a glucose phosphate isomerase deficiency. This is the first report of priapism secondary to a defect of erythrocyte metabolism.

The continuous production of glucose isomerase

Biotechnology Letters, 1981
It is shown that the enzyme glucose isomerase may be produced effectively by suitable continuous culture techniques using species of Arthrobacter and Mycobacterium. Carbon-limited growth conditions gave better carbon conversion efficiencies and higher specific enzyme activities than batch or nitrogen-limited conditions.
