Abstract
This study aims to describe the global detection and functional inference of hypothetical protein CA803_03125 from Staphylococcus aureus
SO-1977. Computational methods were utilized to study this protein based on sequence similarity and presence of known protein
domains. The BLASTp result revealed a significant similarity between the hypothetical protein (CA803_03125) and ADP-ribose hydrolase
protein from four S. aureus strains (MW2, MRSA252, COL, and N315). Evolutionary tree diagram revealed a close relationship between the
hypothetical protein and proteins of MW2 and COL strains. The physicochemical characterization revealed that all proteins were found to
be stable, soluble, hydrophilic and acidic in their nature. The Macro domain was found to exist within all proteins. Moreover, the proteins
were of pronounced similarity in terms of primary, secondary and tertiary organization. The protein CA803_03125 (SO-1977) is already
known and well characterized as ADP-ribose hydrolase; therefore, we would recommend that its NCBI data has to be updated to be
submitted under the name of ADP-ribose hydrolase.
