Image Aspartate transaminase.png thumb right 300px Aspartatetransaminase from E. coli with Pyridoxal 5 Phosphate cofactor In biochemistry , a transaminase or an aminotransferase is an enzyme that catalyze s a type of reaction between an amino acid and an alpha keto acid &alpha keto acid . To be specific, this reaction transamination involves removing the amino group from the amino acid, leaving behind an keto acid, and transferring it to the reactant keto acid and converting it into an amino acid. Some transamination activities of the ribosome have been found to be catalyzed by so called ribozymes RNA enzymes . Examples being the hammerhead ribozyme , the VS ribozyme and the hairpin ribozyme . The transaminase enzymes are important in the production of various amino acids, and measuring the concentration s of various transaminases in the blood is important in the diagnosing and tracking many disease s. Transaminases require the coenzyme pyridoxal phosphate , which is converted into pyridoxamine in the first phase of the reaction, when an amino acid is converted into a keto acid. Enzyme bound pyridoxamine in turn reacts with pyruvate , oxaloacetate , or alpha ketoglutarate , giving alanine , aspartic acid , or glutamic acid , respectively. Many transamination reactions occur in tissues, catalysed by transaminases specific for a particular amino keto acid pair. The reactions are readily reversible, the direction being determined by which of the reactants are in excess. The specific ... acid and pyruvic acid to make alpha ketoglutaric acid and alanine is called glutamic pyruvic transaminase or GPT for short. Tissue transaminase activities can be investigated by incubating a homogenate ... plays a key role in funneling nitrogen from amino acid metabolism to aspartate and glutamate for conversion ...
