Secondary Metabolites: Threonine Biosynthesis from Aspartate
Adenosine triphosphate + L-Homoserine → Adenosine diphosphate + Hydrogen Ion + O-Phosphohomoserine
O-Phosphohomoserine + Water → L-Threonine + Phosphate
L-Aspartate-semialdehyde + Pyruvic acid ↔ L-2,3-Dihydrodipicolinate + 2 Water
Hydrogen Ion + L-Aspartyl-4-phosphate + NADPH → L-Aspartate-semialdehyde + NADP + Phosphate
Hydrogen Ion + L-Aspartate-semialdehyde + NADPH → L-Homoserine + NADP
4-hydroxy-tetrahydrodipicolinate synthase
Adenosine triphosphate + L-Aspartic acid → Adenosine diphosphate + L-Aspartyl-4-phosphate
aspartate kinase / homoserine dehydrogenase
