NADP-dependent glyceraldehyde-3-phosphate dehydrogenase
Methylmalonate-semialdehyde dehydrogenase [acylating], mitochondrial
Adenosine triphosphate + L-Aspartic acid → Adenosine diphosphate + L-Aspartyl-4-phosphate
L-Threonine → (2Z)-2-aminobut-2-enoate + Hydrogen Ion + Water
2-iminobutanoate + Hydrogen Ion + Water → 2-Ketobutyric acid + Ammonium
(2Z)-2-aminobut-2-enoate → 2-iminobutanoate
Probable low-specificity L-threonine aldolase 1
Hydrogen Ion + L-Aspartyl-4-phosphate + NADPH → L-Aspartate-semialdehyde + NADP + Phosphate
L-Glutamic acid + Oxalacetic acid ↔ L-Aspartic acid + Oxoglutaric acid
Adenosine triphosphate + L-Homoserine → Adenosine diphosphate + Hydrogen Ion + O-Phosphohomoserine
aspartate kinase / homoserine dehydrogenase
Threonine dehydratase biosynthetic, chloroplastic
O-Phosphohomoserine + Water → L-Threonine + Phosphate
Hydrogen Ion + L-Aspartate-semialdehyde + NADPH → L-Homoserine + NADP
Aspartate aminotransferase 3, chloroplastic
Acetaldehyde (→) Transport: Arabidopsis thaliana, Cytosol to Arabidopsis thaliana, Cell, Mitochondrion
L-Threonine → Acetaldehyde + Glycine
Acetaldehyde + Coenzyme A + NAD → Acetyl-CoA + Hydrogen Ion + NADH
