Aldehyde dehydrogenase from yeast catalyzes the following reaction: RCHO + NAD/NADP+ + H2O → RCOOH + NADH/NADPH+ + H+. The yeast enzyme requires potassium ions and thiols (glutathione, 2-mercaptoethanol, cysteine) for its activity. It is inhibited by traces of heavy metals, particularly copper. Similar enzymes, but with different requirements for their catalytic activities, have been purified from equine liver and from human erythrocytes. The enzyme from yeast has a molecular weight of 200,000. Creative Enzymes uses its expertise in enzyme manufacturing to supply customers enzymes using for life science research and production of medicines, food, alcohol, beer, fruit juice, fabric, paper, leather goods, etc.  Our products are used worldwide in academic, commercial, and government laboratories in diverse applications, including basic research, drug discovery, cancer research, infectious disease research, microbiology, and personalized medicine.
