MAT1A encodes two liver-specific MAT isoenzymes, such as MATI (MAT1A homo-tetramer) and MATIII (MAT1A homo-dimer), that catalyze the transfer of an adenosyl group of adenosine triphosphate (ATP) to Met to produce SAMe and tripolyphosphate ( MAT2A , and is expressed in all tissues, such as the liver, albeit to a smaller extent ( Figure 1 SAMe serves mainly as a methyl donor in the cell and transfers its methyl group to substrates such as nucleic acids, proteins, lipids, and secondary metabolites with the formation of S-adenosylhomocysteine (SAH, which is also abbreviated as AdoHcy), via transmethylation ( 2
