ABSTRACT

Objective:

In order to identify the function of the mevalonate kinase (MK) which is a key enzyme of the mevalonate pathway (MVA) in Swertia mussotii, and to improve the study of MVA in S. mussotii.

Methods:

According to the SmMK gene sequence of transcriptome of S. mussotii, the specific primers were designed, the cDNA complete sequences was obtained by RT-PCR and the sequence was analyzed using bioinformatics. Prokaryotic expression vector MBP-SmMK was constructed and transformed into Escherichia coli Rosetta (DE3) for expression.

Results:

The results showed that SmMK cDNA complete sequences had a length of 1 164 bp encoding 387 amino acid residues. The SmMK protein shared high identity with other MK proteins of plants. And the protein signal peptide, transmembrane region, location, secondary, and tertiary structures were analyzed and forecasted. The SDS-PAGE results showed that the expressed proteins were consistent with the anticipated size, which was 40 970.

Conclusion:

This work will provide a foundation for research the SmMK protein functional and study MCA in S. mussotii. At the same time, it will supply the basis to improve the production of the isoprenoids.
