Transaminases or aminotransferases are enzymes that catalyze a transamination reaction between an amino acid and an α-keto acid. They are important in the synthesis of amino acids, which form proteins.

Two important transaminase enzymes, aspartate transaminase (AST), and alanine transaminase (ALT), are commonly used as indicators of liver and cardiac health.
