2. AI-Driven Conformational Ensemble Generation
Starting from the initial protein structure, we employed advanced AI algorithms to predict alternative functional states of [3-methyl-2-oxobutanoate dehydrogenase [lipoamide]] kinase, mitochondrial, 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.

Alternative names:
Branched-chain alpha-ketoacid dehydrogenase kinase
Alternative UPACC:
O14874; A8MY43; Q6FGL4; Q96G95; Q96IN5
Background:
The protein, identified by the accession number O14874, functions as a key regulatory enzyme in the metabolism of branched-chain amino acids (BCAAs) such as valine, leucine, and isoleucine. It catalyzes the phosphorylation and inactivation of the branched-chain alpha-ketoacid dehydrogenase complex, pivotal in the catabolic pathways of these amino acids. Known alternatively as Branched-chain alpha-ketoacid dehydrogenase kinase, its activity is crucial for maintaining amino acid balance within the body.
Therapeutic significance:
Branched-chain ketoacid dehydrogenase kinase deficiency, a metabolic disorder linked to this protein, manifests as autism, epilepsy, intellectual disability, and altered BCAA levels. Treatment strategies focusing on dietary BCAA supplementation have shown promise in normalizing plasma BCAA levels, highlighting the protein's potential in therapeutic interventions.
