Viral BONCAT: Detection of HPG incorporation into newly synthesized viral proteins via proteomics

ABSTRACT: BONCAT was adapted and tested as a method for directly quantifying viral production in the ocean. To confirm the successful transfer of host-associated HPG-labeled proteins or peptides into marine viruses, we conducted an independent suite of proteomic experiments with cultured systems to directly assess the production of HPG-labeled viral proteins. We used including Emiliania huxleyi strain CCMP374 and its ~200nm coccolithovirus EhV207 as well as E. coli and its ~50 nm virus T7 as virus-host model systems. These specific model systems were chosen because they represent a range of viral particle sizes and their infection dynamics are well characterized. E. huxleyi/EhV207 also represents an ecologically relevant marine virus-host pair.

While the collective impact of marine viruses has become more apparent over the last decade, a deeper understanding of virus-host dynamics and the role of viruses in nutrient cycling would benefit from direct observations at the single-virus level. We describe two new complementary approaches - stable isotope probing coupled with nanoscale secondary ion mass spectrometry (nanoSIMS) and fluorescence-based biorthogonal non-canonical amino acid tagging (BONCAT) - for studying the activity and bioge ...[more]

Project description:Viral infections are associated with extensive remodeling of the cellular proteome. Viruses encode gene products that manipulate host proteins to redirect cellular processes or subvert antiviral immune responses. One way in which host antiviral proteins antagonize viral infection is by associating with viral genomes and inhibiting essential viral processes. Adenovirus (AdV) encodes gene products from the early E4 region which are necessary for productive infection. Some cellular antiviral proteins are known to be targeted by AdV E4 gene products, resulting in their degradation or mislocalization. However, the full repertoire of host proteins manipulated by viral E4 proteins has not been defined. To identify cellular proteins and processes manipulated by viral products, we developed a global, un-biased proteomics approach to analyze changes to the host proteome during infection with Adenovirus serotype 5 (Ad5) virus. We combined quantification of total protein abundance in the proteome together with an analysis of proteins associated with viral genomes using isolation of Proteins on Nascent DNA (iPOND). By Integrating these proteomics datasets, we identified cellular factors that are degraded in an E4-dependent manner or are associated with the viral genome in the absence of E4 proteins. We further show that some identified proteins exert inhibitory effects on Ad5 infection. Our systems-level analysis reveals cellular processes that are manipulated during Ad5 infection and points to host factors counteracted by early viral proteins as they remodel the host proteome to promote efficient infection. Importance Viral infections stimulate myriad changes to the host cell proteome. As viruses harness cellular processes and counteract host defenses, they impact abundance, modifications, or localization of cellular proteins. Elucidating the dynamic changes to the cellular proteome during viral replication is integral to understanding how virus-host interactions influence the outcome of infection. Adenovirus serotype 5 (Ad5) encodes early gene products from the E4 genomic region that are known to alter host response pathways and promote replication, but the full extent of proteome modifications they mediate is not known. We use an integrated proteomics approach to quantitate protein abundance and protein associations with viral DNA during virus infection. Systems-level analysis identifies cellular proteins and processes impacted in an E4-dependent manner that could overcome potentially inhibitory host defenses. This study provides a global view of Adenovirus-mediated proteome remodeling which can serve as a model to investigate virus-host interactions of DNA viruses.
