ABSTRACT
Objective Sodium-bile acid cotransporter plays an important role in the development of Echinococcus.The present study aimed to clone sodium bile acid cotransporter gene in Echinococcus multilocularis (EmSBACT5) and to analyze the bioinformatics of its coding protein.Methods EmSBACT5 gene was amplified by reverse transcription RCR (RT-PCR) technology and its nucleotide sequence was sequenced.Bioinformatics softwares were used to predict and analyze the physical and chemical properties, hydrophilicity/hydrophobicity, transmembrane domain, post-translational modification sites, structural domain, secondary structure, tertiary structure, subcellular localization and biological functions of the coding protein.Results The complete open reading frame was amplified with 654 bp in length, encoding 217 amino acids.The homology of the nucleic acid sequence and amino acid sequence of EmSBACT5 gene were 98% and 96% with the published SBACT5 in Echinococcus granulosus (EgSBACT5) respectively.Protein analysis results showed that the molecular formula of EmSBACT5 protein was C1141H1797N273O284S11.Its relative molecular mass was 24240 and isoelectric point was 8.99.There were 9 post-translational modification sites and 4 typical domains.Alpha helical, β-sheet, β-turn and random coil accounted for 29.95%, 31.80%, 7.83% and 30.41%, respectively.This protein was a hydrophobic membrane protein and was mainly located in the cytoplasmic membrane, and it might play a role in the processes of material transport and signal transmission.Conclusion The EmSBACT5 gene was cloned successfully and the informatics characteristics of its coding protein were obtained, which provides basic information for prevention and control of echinococcosis.
