Background:

Single-molecule force spectroscopy generates force-distance (F-D) curves, offering insights into protein interactions.
Analyzing F-D curves is challenging, requiring objective criteria and additional data for accurate interpretation.

Purpose of the Study:

To develop a software assistant that simplifies the analysis of F-D curves from single membrane proteins.
To integrate force-interaction patterns with protein topology and 3D structure for enhanced interpretation.

Main Methods:

Development of a software assistant that represents F-D curve data and membrane protein topology.
Integration of bioinformatic features, web queries, and visualization tools (e.g., Jmol).

Main Results:

The software provides a basis for detailed interpretation of protein structure and molecular interactions.
Integrated features facilitate the analysis of membrane protein folding, structure, stability, and function.

Conclusions:

The developed software assistant significantly aids in the interpretation of complex single-molecule force spectroscopy data.
This tool enhances understanding of membrane protein structure-function relationships by combining biophysical and structural information.
