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 noun trans· am· i· na· tion ˌtran (t)s-ˌam-ə-ˈnā-shən, ˌtranz- : a reversible oxidation-reduction reaction in which an amino group is transferred typically from an alpha-amino acid to the carbonyl carbon atom of an alpha-keto acid More from Merriam-Webster on transamination Britannica.com: Encyclopedia article about transamination
