Application

Application Comment Organism
synthesis recombination of MAT genes from Escherichia coli, Saccharomyces cerevisiae, and Streptomyces spectabilis by DNA shuffling and transformation into Pichia pastoris. In the two best recombinant strains, the MAT activities are respectively 201% and 65% higher than the recombinant strains containing the starting MAT genes, and the SAM concentration increases by 103% and 65%, respectively. A 6.14 g/l of SAM production is reached in a 500 l bioreactor with the best recombinant strain Saccharomyces cerevisiae

The K18R mutation of Streptomyces spectabilis probably result in the increased activity of the best MAT.
