MetaCyc Pathway: superpathway of L-threonine biosynthesis in Sphingobium sp. HT1-2

Aspartate transaminase (in reverse):
oxaloacetate + L-glutamate→L-aspartate + 2-oxoglutarate (EC 2.6.1.1)

Aspartate kinase:
L-aspartate + ATP→L-aspartyl-4-phosphate + ADP (EC 2.7.2.4)

Aspartate-semialdehyde dehydrogenase (in reverse):
L-aspartyl-4-phosphate + NADPH + H⁺→L-aspartate 4-semialdehyde + NADP⁺ + phosphate (EC 1.2.1.11)

Homoserine dehydrogenase (in reverse):
L-aspartate 4-semialdehyde + NAD(P)H + H⁺→L-homoserine + NAD(P)⁺ (EC 1.1.1.3)

Homoserine kinase:
L-homoserine + ATP→O-phospho-L-homoserine + ADP + H⁺ (EC 2.7.1.39)

Threonine synthase:
O-phospho-L-homoserine + H₂O→L-threonine + phosphate (EC 4.2.3.1)

Candidate genes for each reaction are identified from best hits to MetaCyc; by matching EC numbers (which are assigned by TIGRFam, SEED, or best hits to KEGG); or by matching SEED roles to KEGG reactions to MetaCyc reactions. See the "Protein" tab of each gene for more information
