                            A method of producing an α-L-aspartyl-L-phenylalanine-β-ester by forming the α-L-aspartyl-L-phenylalanine-β-ester from L-aspartic acid-α,β-diester and L-phenylalanine using an enzyme or enzyme-containing substance that has an ability to selectively link L-phenylalanine to an α-ester site of the L-aspartic acid-α,β-diester through a peptide bond.
