Uplоаd yоur аnswers tо these questions. Beginning with PLP (Vit. B6), whose structure is given below, drаw out the arrow-pushing mechanism that results in the transfer of the amino group of Ala to PLP as catalyzed by the enzyme alanine aminotransferase. (6 pts.) Name the molecule that ultimately accepts the amino group of Ala in the above alanine aminotransferase reaction. (1 pt.) The α-amino group in the amino acid glutamate can be directly converted to an α-keto compound in a single step with the release of ammonia. This reaction requires a cofactor. Identify the cofactor and the general name for the type of enzyme that catalayzes reactions like these. (2 pts.)
