Background:

Fullerenes, specifically C60, are known to interact with and modify the activity of approximately 20 proteins.
Understanding these interactions is crucial for developing new therapeutic agents and biomaterials.

Purpose of the Study:

To develop and validate a computational algorithm for predicting C60 docking sites on proteins.
To identify novel protein targets for C60 interaction and explore their potential applications.

Main Methods:

Utilized a database of over 1200 protein structures, including drug targets and representative Protein Data Bank entries.
Applied a quantitative algorithm to assess the interaction between C60 and protein surfaces.
Validated predictions against known fullerene-binding proteins and experimental data.

Main Results:

The algorithm accurately predicted C60 docking sites on proteins, with 80% of known fullerene-binding proteins identified within the top 10% of predicted sites.
The model's predictions closely matched experimental observations, confirming its accuracy.
Identified and analyzed the top 10 protein scorers for detailed examination.

Conclusions:

The developed computational approach is a reliable tool for predicting protein-C60 interactions.
New potential protein targets for C60 binding have been identified, offering opportunities for drug development and fullerene-based biomaterials.
