Exploring proteins and protein-ligand complexes through residue interaction networks

Area of Science:

• Structural Biology
• Computational Biology
• Biochemistry

Background:

• Protein structures offer crucial insights into biological functions and mechanisms.
• High-quality structure predictions and molecular simulations generate vast datasets.
• Analyzing large structural datasets can be challenging, obscuring biologically relevant features.

Purpose of the Study:

• To present the Residue Interaction Network (RIN) generator (RING) software as a tool for biological insight discovery.
• To provide a comprehensive guide for constructing detailed RINs for proteins and protein-ligand complexes.
• To demonstrate efficient analysis of single- and multi-state protein structures.

Main Methods:

• Utilizing the RING software, available as a web server and a stand-alone package.
• Performing step-by-step single- and multi-state protein analyses.
• Executing sequential multi-file analysis via the command-line interface.

Main Results:

• Detailed RINs can be constructed for proteins and protein-ligand complexes.
• The RING workflow facilitates the identification of biologically relevant features within structural data.
• The entire analysis process can be completed in under 45 minutes.

Conclusions:

• The RING software effectively condenses complex structural data into manageable Residue Interaction Networks.
• RING provides an accessible method for researchers to gain biological insights from protein structures.
• The protocol is suitable for biologists with limited programming experience.
