Molecule: Aspartate Aminotransferase Chain: A Ec: 2.6.1.1 Other_details: The Coenzyme Pyridoxal 5'-Phosphate In Subunit A Forms A Schiff Base With The Substrate Analog 2- Methylaspartate, And Forms The External Aldimine. But Due To Crystal Lattice Packings The Coenzyme In Subunit B Is Still In The Internal Aldimine With The Side Chain Of Lys 258.;		Organism_scientific: Sus Scrofa Organism_common: Pig Organism_taxid: 9823
