MetaCyc Pathway: superpathway of L-phenylalanine biosynthesis
Inferred from experiment

Pathway diagram: superpathway of L-phenylalanine biosynthesis

If an enzyme name is shown in bold, there is experimental evidence for this enzymatic activity.

Superclasses: BiosynthesisAmino Acids BiosynthesisProteinogenic Amino Acids BiosynthesisL-phenylalanine Biosynthesis

Some taxa known to possess this pathway include : Escherichia coli K-12 substr. MG1655

Expected Taxonomic Range: Bacteria

The aromatic amino acid L-phenylalanine is biosynthesized from the principal precursors D-erythrose 4-phosphate and phosphoenolpyruvate via chorismate, a common precursor of many aromatic compounds including L-tyrosine, L-tryptophan, and several other essential compunds, as shown in the superpathway of chorismate metabolism.

For more information regarding L-phenylalanine biosynthesis see L-phenylalanine biosynthesis I.

Subpathways: L-phenylalanine biosynthesis I, chorismate biosynthesis I, chorismate biosynthesis from 3-dehydroquinate, 3-dehydroquinate biosynthesis I

Variants: L-phenylalanine biosynthesis II, L-phenylalanine biosynthesis III (cytosolic, plants)
