Multi-pass Transmembrane Proteins and β-barrels

Multi-pass Transmembrane Proteins and β-barrels

In multi-pass transmembrane proteins, the polypeptide chain crosses the membrane more than once. The transmembrane polypeptide chain either forms an α-helix or β-strand structure. α-Helix containing multi-pass transmembrane proteins are ubiquitous, whereas β-strand containing ones are mainly found in gram-negative bacteria, mitochondria, and chloroplasts.

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.

Ligand Binding and Linkage

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked. In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Background:

Enzyme Commission (EC) numbers link protein sequences to catalyzed biochemical reactions, essential for understanding biological reproduction and metabolism.
Current enzyme function prediction methods face challenges including complex manual feature engineering, sequence embedding difficulties, and handling significant inter-enzyme distribution gaps.
Existing models often extract single-view features, limiting their ability to capture the complexity of enzyme data and predict multilevel functions effectively.

Purpose of the Study:

To address the limitations of existing enzyme function prediction methods.
To propose a novel multilevel enzyme function prediction model (SMENET) leveraging multi-view semantics.
To improve the accuracy and comprehensiveness of enzyme function prediction.

Main Methods:

Utilized a protein large language model to extract rich semantic information from enzyme sequences.
Employed multiple information extraction network modules to process semantic data.
Integrated diverse feature views using Biologic Semantic Attention and a multi-view adaptive fusion network for optimal representation extraction.

Main Results:

The proposed SMENET model demonstrated significant effectiveness in multilevel enzyme function prediction across multiple datasets.
The multi-view semantic approach successfully addressed the limitations of single-view feature extraction and distribution gaps.
Experimental validation confirmed the superiority of SMENET over existing methods.

Conclusions:

SMENET offers a robust and effective approach for enhancing enzyme function prediction by integrating multi-view semantic information.
The model's ability to capture complex enzyme data representations paves the way for more accurate functional annotations.
The study provides a valuable tool for researchers in biochemistry and bioinformatics, with code and data publicly available.
