2. AI-Driven Conformational Ensemble Generation
Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of Cytochrome P450 2C8, including large-scale conformational changes along "soft" collective coordinates. Through molecular simulations with AI-enhanced sampling and trajectory clustering, we explored the broad conformational space of the protein and identified its representative structures. Utilizing diffusion-based AI models and active learning AutoML, we generated a statistically robust ensemble of equilibrium protein conformations that capture the receptor's full dynamic behavior, providing a robust foundation for accurate structure-based drug design.

3. Binding pockets identification and characterization
We employed the AI-based pocket prediction module to discover orthosteric, allosteric, hidden, and cryptic binding pockets on the protein’s surface. Our technique integrates the LLM-driven literature search and structure-aware ensemble-based pocket detection algorithm that utilizes previously established protein dynamics. Tentative pockets are then subject to AI scoring and ranking with simultaneous detection of false positives. In the final step, the AI model assesses the druggability of each pocket enabling a comprehensive selection of the most promising pockets for further targeting.

Background:
Cytochrome P450 2C8, known by alternative names such as CYPIIC8 and Cytochrome P450 MP-20, plays a crucial role in the metabolism of fatty acids, steroid hormones, and vitamins. This enzyme, encoded by the gene P10632, is a cytochrome P450 monooxygenase that utilizes molecular oxygen to insert one oxygen atom into a substrate while reducing the second into a water molecule. It is particularly noted for its ability to catalyze the epoxidation of polyunsaturated fatty acids and the hydroxylation of carbon-hydrogen bonds, including the metabolism of all trans-retinoic acid and estrogen steroid hormones.
Therapeutic significance:
Understanding the role of Cytochrome P450 2C8 could open doors to potential therapeutic strategies. Its involvement in the metabolism of crucial biological molecules highlights its significance in maintaining physiological balance and the potential for targeting in drug discovery efforts.
