WebTransamination is the most common reaction type catalyzed by PLP-dependent enzymes. It is a biologically important process by which living cells reversibly transfer the amino group from an amine (e.g., γ -aminobutyrate) or α -amino acid (e.g., aspartate) to an α-keto carboxylic acid (e.g., α -ketoglutarate). ( Figure 2). WebReaction mechanism [ edit] The reaction mechanism involves the acylation and activation of the acid 1 to the mixed anhydride 3. The amide will serve as a nucleophile for the cyclization forming the azlactone 4. Deprotonation and acylation of the azlactone forms the key carbon -carbon bond.
