Viral Structure

Viral Structure

Viruses are extraordinarily diverse in shape and size, but they all have several structural features in common. All viruses have a core that contains a DNA- or RNA-based genome. The core is surrounded by a protective coat of proteins called the capsid. The capsid is composed of subunits called capsomeres. The capsid and genome-containing core are together known as the nucleocapsid.

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

Pharmacokinetics: Drug–Food and Drug–Viral Interactions

A drug interaction occurs when the concurrent use of another drug, food, or an external substance alters the pharmacological activity of a drug. This interaction can modify the action of the original drug, affecting its effectiveness and safety.Drug–food interactions are significant as they impact drug absorption, metabolism, and excretion. For example, grapefruit juice is a well-known disruptor of drug metabolism. It inhibits the cytochrome P450 3A4 enzyme, crucial for the metabolism of...

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Viral Mutations

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

Experimental Determination of Chemical Formula

Experimental Determination of Chemical Formula

The elemental makeup of a compound defines its chemical identity, and chemical formulas are the most concise way of representing this elemental makeup. When a compound’s formula is unknown, measuring the mass of its constituent elements is often the first step in determining the formula experimentally.

Area of Science:

Proteomics
Molecular Biology
Virology

Background:

Viral and pathogen proteins often rely on host protein complexes due to small genomes.
Studying host-pathogen interactions is crucial for understanding pathogenicity and viral mechanisms.

Purpose of the Study:

To review proteomic methods for identifying and analyzing protein binding partners.
To present representative studies utilizing these proteomic techniques.

Main Methods:

Methods are categorized into ex situ (e.g., yeast two hybrids, pull-downs, NAPPA) and in situ (e.g., affinity purification, proximity dependent labeling).
Ex situ assays analyze binding outside the cellular environment.
In situ assays analyze binding within the host cell environment.

Main Results:

Both ex situ and in situ methods can generate reliable protein-protein interaction networks.
Representative studies demonstrate the application of these proteomic methods.

Conclusions:

Proteomic methods are powerful tools for interactomics.
Understanding the limitations of chosen methods is essential for experimental design and data interpretation in interactomics.
