실험 절차

3 μl of the same enzyme fraction as used in Example 5 was added to 100 μl of 100 mM borate buffer (pH 9.0) containing 100 mM L-alanine methyl ester hydrochloride, 200 mM L-glutamine and 10 mM EDTA, and allowed to react at 18° C. As a result, as shown in FIG. 3, 83 mM L-alanyl-L-glutamine (L-Ala-L-Gln) was formed in the case of an enzyme-added lot, and the concentration of by-product L-Ala-L-Ala-L-Gln was 1.3 mM. On the other hand, there was scarcely any production of L-Ala-L-Gln observed in an enzyme-non-added lot, and L-Ala-L-Gln production was only about 0.07 mM after reaction for 120 minutes.
