WebThe transamination reaction consists of two half-reactions: the amino group of the first amino substrate is transferred to PLP to produce pyridoxamine 5′-phosphate (PMP) and keto acid (ketone). In the second step, the keto substrate accepts the amino group of PMP to yield a new amino acid (amine) and regenerates PLP [ 5 , 8 ]. WebTransamination (Figure 3) is of central importance in amino acid metabolism, providing pathways for the catabolism of all of the amino acids, except lysine, which does not undergo transamination. Many of these reactions are linked to the amination of 2-oxoglutarate to glutamate or glyoxylate to glycine, which are substrates for oxidative ...
