Characterization of Intestinal Invertase as a Glucosido-Invertase. I. Action on Different Substrates.

The action of invertase preparations.

Characterization of the invertase from Pichia anomala.

Synthesis of invertase (EC 3.2.1.26) in Pichia anomala is controlled by the carbon source in the culture medium. The enzyme was purified to homogeneity from P. anomala cells fully derepressed for invertase synthesis and shown to be a multimeric glycoprotein composed of identical subunits with an apparent molecular mass of 86.5 kDa. The carbohydrate moiety accounts for approx. 30% of the total m...

Immobilized invertase.

Invertase is a commercially important enzyme used for the hydrolysis of sucrose. The hydrolysis of sucrose yields an equimolar mixture of glucose and fructose, known as invert syrup, is widely used in food and beverage industries. This enzyme is also used for the manufacture of artificial honey, plasticizing agents used in cosmetics, pharmaceutical and paper industries as well as enzyme electro...

Date Wastes as Substrate for the Production of a-Amylase and Invertase

Background: In Algeria the date wastes production is estimated at least 85.000 tones. Date wastes is an economic source of carbohydrates for conversion to industrial enzymes because it is readily available and relatively low priced. Objective: The aim of the present study was to investigate the potential of using date wastes as a substrate for the production of a-amylase and invertase. Materia...

Effect of temperature on invertase, invertase inhibitor, and sugars in potato tubers.

The accumulation of reducing sugars in potato tubers exposed to low temperatures occurs with concomitant formation of the enzyme invertase. During the initial period of cold treatment when reducing sugars increase rapidly, invertase formation proceeds until the level of enzyme exceeds that of an endogenous macromolecular invertase inhibitor, resulting in a basal invertase activity. As the rate ...
