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

Participants

Reaction Steps

The reaction solution (250 g) containing 12 weight % (wt %) of L-phenylalanine, a bacterial cell (in an appropriate amount) of MT-11046 produced in Example 1 and water was reacted at 20 degrees centigrade for 24 hours or more. During the reaction, pH of the reaction solution was adjusted to 9.2 with 25% ammonia water. A solid of (S)-β-phenylalanine precipitated under examined condition was observed. The reaction yield of (S)-β-phenylalanine was 62%.
