Cloned(Commentary)

EC Number Cloned (Comment) Organism
3.2.1.3 expression in Pichia pastoris, Saccharomyces cerevisiae or Aspergillus niger. In Pichia pastoris the C320A/E400C double mutant is produced at 75% of the wild-type glucoamylase, while the corresponding single mutants are produced at 1% and 20% of the wild-type level, respectively Aspergillus awamori
