D-Amino Acid Oxidase Mechanism and Biology

The video explores the catabolism of D amino acids, focusing on the enzyme D amino acid oxidase. It explains the mechanism of this enzyme, including the formation of a Schiff base and the production of hydrogen peroxide. The video also discusses the significance of D amino acid oxidase in breaking down bacterial D amino acids, such as D alanine and D glutamate, and the potential implications for human health. Additionally, it covers the glyoxylate pathways and their role in metabolism, concluding with a brief introduction to racemase enzymes.
