In silico functional annotation of a hypothetical protein from Staphylococcus aureus.

Unknown proteins or hypothetical proteins exist but have not been characterized or linked to known genes. Domains of unknown function are experimentally identified proteins with no known functional or structural domain. In this paper, the investigation and characterization of the likely functional aspects of a hypothetical protein, YP_001317347.1, from Staphylococcus aureus was performed using various computational methods and tools. Based on the analysis, the protein has a YbbR domain and is expected to bind ribosomal subunits. The analysis reported here helps in understanding the importance of YbbR domains and will aid in the development of novel antibacterial agents.
