Nucleic Acid Structure

Nucleic Acid Structure

The pentose sugar in DNA is deoxyribose, while in RNA the pentose sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the ribose's second carbon and a hydrogen on the deoxyribose's second carbon. The phosphate residue attaches to the hydroxyl group of the 5′ carbon of one sugar and the hydroxyl group of the 3′ carbon of the sugar of the next nucleotide, which forms a 5′ to 3′ phosphodiester linkage.

Conserved Binding Sites

Conserved Binding Sites

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...

Ligand Binding Sites

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Molecular Shapes

Molecular Shapes

Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.
Two regions of electron density in a diatomic...

Molecular Models

Molecular Models

Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

Background:

Predicting nucleic acid-protein interactions is crucial for understanding biological processes, but remains challenging.
Current sequence-based methods lack structural context, while traditional structure-based methods require experimentally determined protein structures.
High-performance structure prediction tools like AlphaFold2 are computationally intensive, limiting genome-wide applications.

To develop an accurate and efficient method for identifying DNA- and RNA-binding sites on proteins.
To leverage fast protein structure prediction from ESMFold for binding site prediction.
To enable large-scale analysis of nucleic acid-protein interactions and facilitate protein function discovery.

Main Methods:

Developed GLMSite, a geometric graph learning method utilizing ESMFold-predicted protein structures.
Constructed protein structural graphs with residues as nodes and spatial neighbors as edges.
Enhanced node representations using the ProtTrans language model and trained a geometric vector perceptron network.
Integrated geometric embeddings into a common network to learn shared binding characteristics, followed by prediction using fully connected layers.

Main Results:

GLMSite accurately identifies DNA- and RNA-binding sites on proteins.
The method surpasses existing sequence-based prediction tools.
GLMSite's performance is comparable to traditional structure-based methods.
Predictions are valuable for inferring nucleic acid-binding proteins and discovering protein functions.

Conclusions:

GLMSite offers an efficient and accurate approach for predicting nucleic acid-binding sites using predicted protein structures.
