title: [Characteristics of transglucosilase from Aspergillus batatae].
abstract: Action of transglucosilase from Asp. batatae on different substrates is studied. The ratio of transglucosilase (upsilont) and hydrolase (upsilonh) activities on maltose under the action of transglucosilases from different origins is estimated. The degree of transglucosilating (upsilont/(upsilont+upsilon/)) increases with the increase of substrate molar concentration [S]. The ratio of transglucosilase and hydrolytic activities under the interaction of transglucosilase with half-products of starch metabolism is shown to depend on the concentration of glucose, the end product. The elimination of glucose from the incubation medium produces conditions for realization of hydrolytic pathway of the half-products conversion with transglucosilase. Schemes of the combined action of transglucosilase with alpha-amylase and glucoamylase under the starch conversion in enclosed and opened (continuous glucose elimination) systems are given.
