Background: Bovine Seminal Ribonuclease (BS-RNase) is a unique member of the RNase A family found in the bovine seminal fluid. It is recognized for its antiviral and antitumor properties, which make it a potential therapeutic agent. Objective: This study aimed to compare the stability of monomeric and dimeric forms of BS-RNase using in silico methods. Method: The tertiary structures of BS-RNase as monomers and dimers were obtained from the Protein Data Bank, and missing amino acids were modeled using the Modeller server. The predicted structures were validated using SAVES 6 and ProSA web tools. Molecular dynamics simulations were performed using GROMACS, and the resulting RMSD, RMSF, and Rg plots were analyzed. Results: The results indicated that the monomer\\\\\\\'s ERRAT score, Ramachandran plot, and Z-score were better than the dimer\\\\\\\'s. RMSD, RMSF, and Rg plots were favorable for both structures, with the monomer showing better stability than the dimer. Conclusion: Consequently, the monomeric form of BS-RNase is more stable than its dimeric form, and the monomer can be more reliably used in pharmaceutical studies.
