ASPARTATE AMINOTRANSFERASE A 412 Sus scrofa EC#: 2.6.1.1 IUBMB 2.6.1.3 IUBMB
Mutation: D63N, E288Q, E376Q
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.
