Aim The purpose of this study was to conduct further bioinformatics analysis of the five hemolysin oftreponema pallidum,and to provide evidence for the pathogenic mechanism of hemolysin family proteins in the pathogene-sis oftreponema pallidum.Methods:The general properties of the syphilis family proteins,signal peptides,glycosyla-tion,phosphorylation sites,subcellular positions,secondary structures,functional domains,and antigen epitopes were ana-lyzed by bioinformatic analysis methods using NCBI,BLAST,CDD,BioEdit,ExPASy,SignalP,TMHMM,MEGA,PSORTb 3.0,ABCpred andother bioinformatics analysis m...
