TRANSAMINASE

n. enzyme found in most plant and animal tissue

In biochemistry, a transaminase or an aminotransferase is an enzyme that catalyzes a type of reaction between an amino acid and an α-keto acid. Specifically, this reaction (transamination) involves removing the amino group from the amino acid, leaving behind an α-keto acid, and transferring it to the reactant α-keto acid and converting it into an amino acid. The enzymes are important in the production of various amino acids, and measuring the  concentrations of various transaminases in the blood is important in the diagnosing and tracking many diseases. Most transaminases require the coenzyme pyridoxal-phosphate.
