Amino transferases, also known as transaminases, are enzymes that facilitate the transfer of an amino group from an amino acid to a keto acid. This process is crucial in amino acid metabolism, helping to synthesize and break down amino acids, which are the building blocks of proteins. These enzymes play a significant role in the urea cycle and the synthesis of neurotransmitters. Common examples of amino transferases include aspartate aminotransferase (AST) and alanine aminotransferase (ALT), which are often measured in blood tests to assess liver function and overall health.
