L-Phenylalanine → (3S)-3-amino-3-phenylpropanoic acid

Participants

Reaction Steps

The reaction solution (250 g) containing 36 weight % (wt %) of L-phenylalanine, a bacterial cell (in an appropriate amount) of MT-11046 produced in Example 1 and water was reacted at each temperature shown in Table 6 for 24 hours or more. During the reaction, pH of the reaction solution was adjusted to 8.0 with 25% ammonia water. A solid of (S)-β-phenylalanine precipitated under all examined conditions was observed. The reaction yields of (S)-β-phenylalaninein respective temperatures are shown in Table 6.
