Summary
Researchers developed a machine learning model to predict protein hydrogen exchange. This method aids in understanding protein interactions and disease mechanisms by identifying key residues.
Area of Science:
- Biochemistry
- Computational Biology
- Structural Biology
Background:
- Protein hydrogen exchange is crucial for understanding protein-protein interactions and disease mechanisms.
- Factors influencing hydrogen exchange include hydrogen bonds, solvent accessibility, and residue proximity.
- A universal predictive method for identifying hydrogen-exchanging residues across diverse proteins is currently unavailable.
Purpose of the Study:
- To develop a general machine learning method for predicting protein residue hydrogen exchange.
- To create a transferable predictive model applicable to a broad range of proteins.
Main Methods:
- A random forest machine learning approach was employed.
- The model was trained and validated using data from the Start2Fold database, comprising 13,306 residues.
Main Results:
- The developed method achieved an out-of-bag error of 20.3%.
- On a test set, the model demonstrated an accuracy of 0.79, recall of 0.74, precision of 0.82, and F1 score of 0.78.
Conclusions:
- The machine learning model effectively predicts protein residue hydrogen exchange.
- This predictive capability offers valuable insights into protein function, genetic variants, and disease processes.

Amino acids
106.1K
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Amino Acid Catabolism
1.2K
Microorganisms rely on proteins as an essential carbon and energy source, particularly in environments with limited polysaccharides or lipids. However, proteins are too large to cross the plasma membrane unaided, necessitating enzymatic degradation. Microbes secrete extracellular proteases and peptidases that hydrolyze proteins into peptides, which can then be transported across the membrane. Once inside the cell, intracellular proteases degrade these peptides into free amino acids, which...

Amino Acid Biosynthetic Pathways
1.3K
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

Hydrogen Bonds
134.3K
Hydrogen bonds are weak attractions between atoms that have formed other chemical bonds. One of these atoms is electronegative, like oxygen, and has a partial negative charge. The other is a hydrogen atom that has bonded with another electronegative atom and has a partial positive charge.
Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....

Hydrogen Bonds
15.0K
A hydrogen bond is formed when a weakly positive hydrogen atom already bonded to one electronegative atom (for example, the oxygen in the water molecule) is attracted to another electronegative atom from another polar molecule, such as water (H2O), hydrogen fluoride (HF), or ammonia (NH3). The huge electronegativity difference between the H atom (2.1) and the atom to which it is bonded (4.0 for an F atom, 3.5 for an O atom, or 3.0 for an N atom), combined with the very small size of an H atom...

Gas Exchange and Transport
77.1K
Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.
