- An example of the present invention is a glycosyltransferase protein for transferring glucose to the steviol glycoside, a recombinant microorganism expressing the enzyme protein, the cells of the microorganism, the cell lysate of the microorganism, the culture of the microorganism, and extracts thereof It relates to a composition for the production of steviol glycosides comprising at least one selected from the group consisting of.
- the enzyme protein according to the present invention does not produce as a by-product or produces a very small amount of a compound having a peak corresponding to an elution time of 14.5 to 15.5 minutes in the HPLC analysis graph. Accordingly, the enzyme protein according to the present invention has a higher conversion rate of Reb D/E than EUGT11 in a mixed substrate containing Reb A and stevioside, and further, has a characteristic that increases as the enzyme reaction time elapses.

- the composition for producing steviol glycoside may further include a substrate comprising at least one selected from the group consisting of stevioside and Reb A, for example, stevioside or Reb A alone substrate, or a substrate thereof It may be a mixed substrate.
- the mixed substrate may be a mixture of stevioside or Reb A, or a stevia extract containing stevioside or Reb A.
- reaction temperature and reaction pH conditions using the UDP-glucosyltransferase or the enzyme-producing microorganism are as described above in the reaction temperature and reaction pH conditions of the enzyme. It's like a bar.

- Plasmid-transformed yeast prepared in Example 1 was selected in SC (synthetic complete) medium using URA-drop out mix, and the selected yeast was induced to express the enzyme through liquid culture.
- colonies selected in SC-Ura solid medium were inoculated into a test tube containing 3 mL SC-Ura liquid medium and cultured overnight.
- the concentration of the cultured cells was checked by measuring the absorbance of OD 600 , and inoculated so that the absorbance of OD 600 was finally 0.1 (final) in a 250 mL flask containing 25 mL of SC-Ura liquid medium and cultured for 24 hours (30°C, 240 rpm).
- the same amount of YPG medium was added and the cells were cultured secondarily for 24 hours.
- the secondary cultured cells were collected by centrifugation (4,000 rpm, 10 min).
- the conversion rate through the enzymatic reaction showed no activity such as EcUGT and OsiUGT as a result of the initial 3 hour reaction, and TaUGT, an initial putative protein, similarly to EUGT11, reduced Reb A to Reb D conversion by 40-45%. was converted, and it was confirmed that the enzyme had about 30% improvement in activity than HvUGT (30-35% conversion).
- the order of the conversion rates of the three enzymes showed a similar tendency to the reaction for 3 hours.
- the result of the enzymatic reaction in FIG. 2 the result of the conversion reaction using RA40 substrate for 5 hours, blue indicates the HPLC chromatogram for the reaction of TaUGT, and in the case of EUGT11, the black indicates the HPLC chromatogram.
- the RA40 substrate is converted to Reb E and Reb D and no by-products are produced.
- the HPLC area of by-products corresponding to 15.1 minutes is 16%. Therefore, the overall conversion rate of Reb E and D decreases. This appears to have occurred as a side reaction of the Reb E product.
- the results of the enzyme reaction in FIG. 3 are the results of the 20-hour conversion reaction using the RA40 substrate.
- the TaUGT enzyme according to the present invention is superior to HvUGT as it only has a high Reb D conversion rate for Reb A alone substrate, and furthermore, for a mixed substrate containing Reb A and stevioside, the total conversion rate of Reb D/E (%) is not only higher than EUGT11, but also increases as the enzymatic reaction time elapses, so it is very useful because it can produce a high content of Red D/E as a substrate for industrially producing steviol glycosides, for example, Reb M.
