Microbial and viral proteins

Microbial and viral proteins represent a vast and heterogeneous group of molecules derived from pathogenic organisms such as bacteria, viruses, fungi, and parasites [NIH, 2023]. These proteins are essential for the survival, replication, and virulence of the pathogen, performing functions ranging from the catalysis of biochemical reactions to the structural assembly of viral capsids or bacterial cell walls [UniProt, 2024]. In therapeutic development, specific proteins within this category are selected as targets for antimicrobial and antiviral agents to disrupt the pathogen's life cycle without harming the host [StatPearls, 2023]. Examples include the targeting of viral neuraminidase in influenza or bacterial transpeptidases in streptococcal infections. However, the term Microbial and viral proteins is a high-level classification rather than a specific therapeutic target, making it too broad for precise drug-target mapping in clinical or biochemical databases. Consequently, while these proteins are the foundation of infectious disease pharmacology, they must be identified individually to be considered actionable drug targets [PubMed, 2022].

Mechanisms include the inhibition of bacterial cell wall synthesis, disruption of viral protease activity, inhibition of viral RNA-dependent RNA polymerase, and interference with bacterial DNA gyrase or topoisomerase [StatPearls, 2023].
