Biosynthesis of Inulinases by Bacillus Bacteria
The optimal parameters for the producer growth were as follows: pH 7.0, 33–35°C, growth duration 72 h, and the presence of reduced mineral nitrogen or organic nitrogen was necessary for the enzyme biosynthesis. Expand
Purification and Characterization of Lipase from Wheat (Triticum aestivum L.) Germ
A method of isolation and purification of lipase (EC from the germ of wheat (Triticum aestivumL.) is described. An electrophoretically homogeneous preparation of the enzyme (specificExpand
[Purification and characterization of lipases from wheat germ].
Homogeneous preparation of the lipase exhibited high thermal stability: over 20% of original activity was retained after incubation of the preparation at high temperatures (60-90 degrees) for 1 h at pH 8.0. Expand
Identification of Catalytically Active Groups in Inulinase from Bacillus polymyxa 722
The dependence of inulinase activity on pH, measurements of pK value, calculation of the ionization heat, photoinactivation with methylene blue, and inhibition with p-chloromercuribenzoate suggest that the active center of this enzyme contains imidazole and sulfhydryl groups. Expand
Preparation and Characterization of Immobilized Aspergillus awamori466 Glucoamylase
Glucoamylase from Aspergillus awamori466 was immobilized on various supports. The enzyme sorption depends on its amount, the type of support, and immobilization conditions. The kinetics of acidicExpand
Identification of Catalytically Active Groups of Penicillium canescens F-436 β-Galactosidase
The functional groups of Penicillium canescens F-436 b-galactosidase have been identified and a mechanism for the participation of these groups in the cleavage of the glycoside bond in lactose is proposed. Expand
Effect of Metabolites of γ-Aminobutyric Shunt on Activities of NAD- and NADP-Isocitrate Dehydrogenases and Aconitate Hydratase from Higher Plants
The obtained data point to a similar pattern of the effect of intermediates of γ-aminobutyric shunt on the studied enzymatic activities for both photosynthetic tissues (pea leaves) and those with acidifying, transport, and digestive functions (maize scutellum). Expand
Identification of Catalytically Active Groups of Wheat Germ Lipoxygenase
Dependences of lipoxygenase activity on pH, ionization enthalpies of various chemical groups, photoinactivation of the enzyme, and effects of specific reagents (p-CMB, DPF, and PMSF) were studied toExpand
