Accepted name: phenylalanine aminomutase (L-β-phenylalanine forming)
Reaction: L-phenylalanine = L-β-phenylalanine
Glossary: L-β-phenylalanine = (R)-3-amino-3-phenylpropanoate
Systematic name: L-phenylalanine 2,3-aminomutase [(R)-3-amino-3-phenylpropanoate-forming]
Comments: The enzyme contains the cofactor 3,5-dihydro-5-methylidene-4H-imidazol-4-one (MIO). This unique cofactor is formed autocatalytically by cyclization and dehydration of the three amino-acid residues alanine, serine and glycine. cf. EC, phenylalanine aminomutase (D-β-phenylalanine forming).
