Transamination ( transfer of amino group from amino acid to a keto acid) is undergone by all amino acids except_______ |
Threonine and lysine |
|
|
Aminotransferases or transaminases are found in the |
cytosol of cells |
|
|
What is the role of vitamin b6 ad a coenzyme for transaminases |
B6 also known as pyridoxyl phosphate are found covalently attached to lysine amino acids at the active sites of those enzymes (transaminases). It receives the amino group from the amino acid first before transferring it to the alpha ketoglutarate |
