Abstract:

Objective To use pan-genomics and subtractive proteomics techniques to screen the new antibacterial targets from the Staphylococcus aureus genome, and to lay the foundation for the development of anti-Staphylococcus aureus drugs. Methods The genome sequencing data of 50 strains with sequencing level Complete were collected by searching the whole genome sequencing data in the National Center for Biotechnology Information (NCBI) Database with Staphylococcus aureus as the keyword;BPGA tool was used to conduct the pan-genomics analysis on the genomic data to obtain the core genes of Staphylococcus aureus; subtractive proteomics technique was used to screen the potential antibacterial targets from the core genes. These potential antibacterial targets were used as the receptors; LibDock software was used to screen the potential anti-Staphylococcus aureus drugs from the US Food and Drug Administration (FDA)-approved drug library; molecular docking technology was used to analyze the binding abilities of the drugs and targets. Results There were 14 379 gene families in the 50 Staphylococcus aureus genomes, of which 1 620 were the core genes. The subtractive proteomics analysis results showed that tyrosine autokinase 1335 was the potential anti-Staphylococcus aureus target. LibDock software screened out nine compounds, including balofloxacin, tenofovir disoproxil fumarate, and adefovir, that may exert anti-Staphylococcus aureus effects on this target protein. The molecular docking results showed there was good binding abilities between the targets and the compounds. Conclusion Tyrosine autokinase may be the potential target for anti-Staphylococcus aureus.
