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 ). WebBecause transamination reactions are reversible they can be used to remove nitrogen from amino acids or to transfer nitrogen to α-keto acids to form amino acids. They participate in both amino acid degradation and amino acid synthesis. Glutamate dehydrogenase catalyzes the oxidative deamination of glutamate. houzz penthouse paint colors
