After thecomplete genome extraction of the strain was performed, the genomic DNA was partiallydigested by restriction enzyme Sau3AⅠ, the DNA fragments from 1 to 5Kb was clonedinto prokaryote expression vector pET-28a-c, and transformed host bacteria. The resultsshowed that we succeeded in constructing the gene expression library of haemophilusparasuis serovar 5, which is fundamental for the study of advanced gene screening. Inaddition, primer design was performed based on haemophilus influenzae in this study. In addition, PCR was performed by using genomic DNA of haemophilus parasuisserovar 5 as the template. The results demonstrated that we obtained two neo-gene:23SrRNA gene(conserved gene belonging to the large-subunit of ribosome) and adenylatecyclase gene(encodes adenylate cyclase and participates in converting adenyl nucleosidetriphosphate to cyclic adenosine3",5"-monophosphate). Furthermore, the phylogeneticanalyses between the species was performed, and neighbor-joining tree was constructedbased on comparison of 23S rRNA gene sequences, so it was illuminated betweenHaemophilus parasuis and other species in molecular evolution relationship.

The shorter variant mHemk2 is 1696 bp in length encoding a putative mouse protein of 14.7 kDa, consisting of 138 amino acid residues.In protein data bank annotations, Hemk has previously been classed among methyltransferases methylating N6-adenine or N4-cytidine in DNA because of the presence of S-adenosyl-L-methionine binding motif and of an NPPY motif in the protein.
在蛋白数据库的注释中,由于在Hemk蛋白中存在S-腺苷-L-甲硫氨酸结合基序和一个NPPY基序,因此,在蛋白库的说明中已经将Hemk蛋白归类于能甲基化DNA中N6-腺嘌呤或N4-胞嘧啶的甲基转移酶。
