Summary
Structural genomics of Epstein-Barr virus (EBV) proteins faced expression and solubility challenges. High-throughput crystallization screening enabled solving structures of difficult EBV proteins.
Area of Science:
- Virology
- Structural Biology
- Genomics
Background:
- Epstein-Barr virus (EBV) is a human herpesvirus linked to various diseases.
- EBV's genome encodes 86 proteins, presenting targets for structural studies.
Purpose of the Study:
- To conduct a structural genomics project on EBV proteins.
- To express and determine the structures of selected EBV open reading frames.
Main Methods:
- Selected 23 EBV open reading frames based on updated genome annotation and predicted properties.
- Expressed proteins in Escherichia coli, facing significant expression and solubility issues.
- Employed robotic nanolitre-drop crystallization trials for soluble proteins.
Main Results:
- Despite challenges, eight EBV proteins were found to be soluble.
- Five soluble proteins were successfully crystallized.
- Four EBV protein structures were determined.
Conclusions:
- High-throughput miniaturized crystallization screening was crucial for success with difficult EBV proteins.
- Individualized approaches were necessary for protein expression and purification.
- This study provides structural insights into EBV proteins.

01:26Size and Structure of Viral Genomes
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
00:58Genomic DNA in Eukaryotes
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.
01:29Viruses of Archaea
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...

Bacteriophages are found throughout the human body. They may even outnumber eukaryotic viruses, forming an important and dynamic component of the human virome. Indeed, phages represent the most abundant viral entities, with densities in the gut reaching up to 10⁹ particles per gram of fecal matter, and many belonging to orders such as Caudovirales and Microviridae, while a substantial proportion remains unclassified as viral “dark matter.”Lysogeny and Genetic ExchangeIn the gut, bacteriophages...
