Multiple viral enzymes and replication pathways

Multiple viral enzymes and replication pathways refer to the collective set of molecular components and biochemical processes required for a virus to infect a host cell and produce progeny. This includes key enzymes such as viral polymerases (RNA-dependent RNA polymerase, DNA polymerase, reverse transcriptase), proteases, integrases, and neuraminidases, as well as structural proteins involved in entry and assembly (NIH, 2023). Drugs targeting these pathways often aim to disrupt the viral lifecycle at specific stages, such as inhibiting genome replication or preventing the maturation of viral proteins (Nature Reviews Drug Discovery, 2021). While many antivirals are highly specific to a single virus, broad-spectrum agents may target conserved motifs across multiple viral families (PubMed, 2022). Understanding these pathways is critical for developing therapies against infectious diseases like COVID-19, HIV/AIDS, hepatitis, and influenza (StatPearls, 2023). Because this term describes a broad category of targets rather than a single molecular entity, it is typically used in the context of multi-target drug discovery or broad-spectrum antiviral research.
