- the sequence of the N-terminal amino acid of the oxidoreductase obtained by the separation and purification in Example 5 was transferred to the PVDF membrane after 12% SDS-PAGE electrophoresis (Bio-Rad), followed by a procedure 491 sequencer (Applied) using Edman analysis. Bio system, caliph).
- sequence the internal peptide the sequence of the peptide fragment obtained after the treatment with sequencing trypsin (promega) was analyzed using LTQ-orbitrap mass spectrometer, and then the sequence was determined using PEAKS program.
- Phenol-chloroform mixture (50:50) in the same amount as the amount of the solution was added and mixed for 30 minutes, followed by centrifugation at 4 °C, 4,000 rpm for 10 minutes to obtain a supernatant.
- 0.5 times of the obtained solution was added to the chloroform and slowly mixed, centrifuged at 4 °C, 4,000 rpm for 10 minutes, and the supernatant was obtained and then reacted at 37 °C for 1 hour after RNase treatment to reach the amount of 50 / mL.
- Primers were prepared from the N-terminal amino acid sequence and the internal sequence obtained in Example 7, and the genomic DNA isolated through the procedure of Example 8 was used as a template to obtain a partial DNA fragment of the oxidoreductase.
- a primer specifically attached to the obtained DAN fragment was prepared, and the remaining sequences were obtained by using an inverse PCR method.
- the template used for the inverse PCR was a DNA library that was self-ligated by digesting genomic DNA fragments with Hind III restriction enzymes followed by ligation.
- the gene sequence of the obtained oxidoreductase was digested with BamHI / SalI restriction enzymes, and the fractions were ligated to pETDuet-1 (Novazen) to generate recombinant plasmids, which were transformed into Rosetta-gami2 (DE3), an expression E. coli. I was.
- the obtained transformed E. coli was cultured in a medium containing ampicillin, and when the cell suspension became 0.3 to 0.7, IPTG was added and the expression of the enzyme was induced by further incubating for 15 hours at 20 ° C.
- Agrobacterium sp. Sphingobacterium sp. Or stenotrophomonase sp.
- An enzyme with at least 60% amino acid similarity with the derived SEQ ID NO: 3 was cloned to investigate the glucose degradation reactivity to ginsenosides. Enzymes derived from each microorganism were found to degrade glucose through oxidation to glucose residues of ginsenosides.
- Example 11 The enzyme induced expression in Example 11 was prepared by the enzyme preparation method of Example 2, and then the non-saccharide production activity was measured using ginsenoside CK as a substrate.
- the same amount of ethyl acetate was added, followed by extraction.
- the ethyl acetate layer was dried and dissolved in ethanol, and the activity was measured using a Maldi mass spectrometer.
- Rizobiium sp An enzyme derived from GIN611-derived redox enzyme was reacted according to the above reaction method using flavonoid-based Icarlin, Camelliaside A and Camelliaside B as substrates. As a result of measuring the activity using a mass spectrometer, the oxidation reaction and the glycolysis activity of galactose attached to camelliaside A were confirmed. In addition, the oxidation and glycolytic activity of xylose attached to camelliaside B was confirmed.
