ReadComputational modelling of flavivirus dynamics: The ins and outs
- Computational methods integrating experimental data help elucidate viral life cycle. - Viruses are dynamic and have complex interactions with a variety of host factors. - We can now model the complex interplay of proteomic and genomic components. - Molecular biology, genomics, and computation complement structural methods.
ReadComputational modelling of flavivirus dynamics: The ins and outs
Enveloped viruses such as the flaviviruses represent a significant burden to human health around the world, with hundreds of millions of people each year affected by dengue alone. In an effort to improve our understanding of the molecular basis for the infective mechanisms of these viruses, extensive computational modelling approaches have been applied to elucidate their conformational dynamics.
ReadPartial Intrinsic Disorder Governs the Dengue Capsid Protein Conformational Ensemble
The 11 kDa, positively charged dengue capsid protein (C protein) exists stably as a homodimer and colocalizes with the viral genome within mature viral particles. Its core is composed of four alpha helices encompassing a small hydrophobic patch that may interact with lipids, but approximately 20% of the protein at the N-terminus is intrinsically disordered, making it challenging to elucidate its conformational landscape.
