Abstract

The invention relates to a nucleic acid molecule that codes for a poligalacturonase that is highly efficient at low temperatures between 5°C - 15°C, and the coded enzyme. The invention also relates to vectors, host cells, recombination methods for producing said enzyme, as well as compositions comprising the poligalacturonase. The invention further relates to the use of said enzyme in the degradation of pectin during the production of wine, beer or fruit juice and in the clarification of grape must or fruit juice.
