3, the pcr amplification product of step 1 is cut with EcorI and SalI enzyme, reclaimed LcSUT1 gene (the PCR product about 1.5kb); Yeast expression carrier PDR196 is cut with EcorI and SalI enzyme, reclaim skeleton carrier; The LcSUT1 gene of recovery and the skeleton carrier of recovery are connected, obtain recombinant plasmid, sequencing result shows, obtained purpose plasmid PDR196-LcSUT1 (the EcorI of PDR196 and SalI enzyme cut inserted sequence table between the recognition site sequence 2 from the DNA shown in 5 ' the terminal 118-1686 position Nucleotide).
4, plasmid PDR196-LcSUT1 is imported in the yeast mutants SUSY7/ura3 strain system of SUT gene function disappearance, obtain recombination microzyme A.Plasmid PDR196-StSUT is imported in the yeast mutants SUSY7/ura3 strain system of SUT gene function disappearance, obtain recombination microzyme B (over against shining).The PDR196 empty carrier is imported in the yeast mutants SUSY7/ura3 strain system of SUT gene function disappearance, obtain recombination microzyme C (negative contrast).
It is that (1.7g/L does not have the amino acid yeast nitrogen for the MD substratum of sole carbon source that recombination microzyme A, recombination yeast B, recombination microzyme C are coated in sucrose respectively, 2% sucrose, 5g/L ammonium sulfate, 20mg/L tryptophane and 1.5% agar are adjusted PH=5.0) carried out 30 ℃ of cultured continuously 5 days on the flat board.Observe the yeast colony growing state.
The result as shown in figure 11.Among Figure 11, a represents recombination microzyme A, and b represents recombination microzyme B, and c represents recombination microzyme C.The result shows, is that the growth conditions of a is identical with b in the MD substratum of sole carbon source at sucrose, and c then can not normal growth.Can the encode LCSUT1 albumen of function of presentation of results LcSUT1, yeast mutants strain system that can complementary sucrose transporter afunction makes its normal growth.
