Pectin transeliminase (PTE) was produced by Saccharomyces cerevisiae, Schizosaccharomyces pombe 4683, and Aspergillus niger in the media containing 2% pectin and examined for its characteristics. The Production of the enzyme was higher by Asp. niger than by the two yeast strains, showing that the PTE activity was proportional to reducing power. The enzyme was proved to reduce pectin and produce 4, 5- unsaturated galacturonic acid. The optimum activity of the PTE was found to be at pH 6.0 and
