General description

Invertase is encoded by the SUC2 (Saccharomyces cerevisiae S288C) gene. In yeast this enzyme exist in: glycosylated (secreted) and non-glycosylated (intracellular) form. The external invertase is composed of carbohydrate (50%) and 60,000 D subunits.

Application

Used in the production of confectionary foods and artificial honey.
Invertase from baker′s yeast (S. cerevisiae) has been used:
  • in liquid media (YES) and is used to determine the invertase activity
  • supplemented to the reaction mixture in the extraction and analysis of sugars and starch
  • for sucrose hydrolysis

Biochem/physiol Actions

Invertase hydrolyzes sucrose into glucose and fructose yielding a colorless product, unlike acid hydrolysis which produces colored products.

Other Notes

One unit will hydrolyze 1.0 μmole sucrose to glucose and fructose per minute at pH 4.6 at 25 °C.
