Gene Cloning and Bioinformatics Analysis of Limonene-3-hydroxylase from Schizonepeta tenuifolia
Specific primers were designed based on sequences of
StL
3
OH
gene screened from transcriptome sequencing data of
S. tenuifolia
and the cDNA sequence of
StL
3
OH
gene was cloned by reverse transcription polymerase chain reaction (RT-PCR) and analyzed for its bioinformatics.
Result
2
The
StL3OH
gene cDNA sequence length was 1 598 bp,containing a 1 497 bp long complete open reading frame which encoded 498 amino acids. StL3OH protein had a theoretical relative molecular mass of 56.40 kDa,with a hydrophilic and unstable nature. Bioinformatics analysis showed that StL3OH protein had no signal peptide but had a transmembrane domain which might be located in endoplasmic reticulum. Multiple sequence alignment and cluster analysis showed that the amino acid sequence of MsL3OH protein had a high similarity with StL3OH protein,both of which contained cytochrome P450 heme binding region,belonging to the D subfamily of cytochrome CYP71 family. Codon bias analysis showed that
StL
3
OH
gene preferred guanine/cytosine(G/C) ending codon,with 27 skewed codons, and Nicotiana benthamiana was proven to be the most suitable host for exogenous expression of
StL
3
OH
gene.
Conclusion
2
The cDNA sequence of
StL3OH
gene was cloned from
S. tenuifolia
for the first time,which will provide a basis for further study on the structure and function of StL3OH protein and the regulation mechanism of
StL3OH
gene in the accumulation and biosynthesis of monoterpenes in
