Summary
Snakebite envenomation requires better treatments. This review highlights how understanding snake venom complexity through top-down proteomics and structural analysis can lead to improved antivenoms and biotechnological applications.
Area of Science:
- Biochemistry
- Proteomics
- Toxicology
Background:
- Snakebite envenomation is a significant global health problem with complex venom compositions challenging current treatments.
- Existing immunoglobulin-based antivenom therapy is limited by the intricate nature of snake venoms.
- Understanding venom heterogeneity is crucial for developing effective antivenoms and discovering novel therapeutic agents.
Purpose of the Study:
- To emphasize the importance of characterizing snake venom heterogeneity beyond primary sequences.
- To explore the role of post-translational modifications and protein complexes in venom toxicity.
- To review top-down proteomic workflows for identifying snake venom proteoforms and discuss advanced structural characterization techniques.
Main Methods:
- Review of current top-down proteomic workflows for snake venom analysis.
- Discussion of advanced separation, instrumentation, and data processing strategies for proteoform identification.
- Evaluation of existing and complementary high-resolution structural bioanalytical techniques (mass spectrometry, X-ray crystallography, cryo-EM).
Main Results:
- Bottom-up proteomics inadequately captures venom heterogeneity (proteoforms, protein interactions).
- Top-down proteomics offers a pathway to identify diverse snake venom proteoforms.
- High-resolution structural techniques are needed to fully elucidate protein structures and interactions.
Conclusions:
- Characterizing snake venom heterogeneity, including proteoforms and higher-order structures, is essential for advancing antivenom development.
- Integrating top-down proteomics and advanced structural biology techniques will enhance our understanding of venom complexity.
- This expanded analytical toolbox will drive innovation in therapeutic and biotechnological applications derived from snake venoms.

12.5K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

6.4K
Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence....

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

7.3K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...
