실험 절차

Into a flask containing 520 mg of a substrate 7-methoxy-2-tetralone, 10 mg of sodium formate, 3 mg of NAD+, 1.57 mg of L-alanine, and 20 mg of pyridoxal phosphate, a culture fluid of the recombinant E. coli HB101 (pNMTAPAF), obtained in Example 29, which expresses MTA, PALDH, and FDH was added so that total volume was 30 ml. The resultant product was stirred at 35° C. for 28 hours while being adjusted to a pH of 6.3 by drippage of 5 N aqueous solution of formic acid. The rate of conversion into 7-methoxy-2-aminotetraline after the reaction was 92.6%. The absolute configuration of 7-methoxy-2-aminotetraline was (S), and the optical purity was 98.1% e.e.
