Small Protein Structure Prediction
What Are Small Proteins?
Small proteins—typically fewer than 100 amino acids—are increasingly recognized for their crucial roles in signaling, immunity, and synthetic biology. However, because of their size, flexibility, and tendency toward intrinsic disorder, they are often difficult to study experimentally. Therefore, small protein structure prediction provides a powerful computational solution, enabling researchers to model their 3D shapes, uncover functional mechanisms, and as a result, accelerate applications in drug discovery, vaccine design, and peptide engineering.
Why Small Protein Structure Prediction Matters
Understanding the structure of small proteins is essential for unlocking their functions. For example, accurate modeling allows scientists to identify new druggable motifs and binding sites. In addition, predicting small protein structures supports vaccine development by enabling precise epitope modeling. Moreover, it empowers synthetic biology by guiding the design of antimicrobial peptides and regulatory microproteins.
In contrast, without reliable predictions, many small proteins remain functionally uncharacterized. Consequently, researchers risk overlooking valuable therapeutic opportunities.
Biointelix Workflow for Small Protein Structure Prediction
At Biointelix, we use an integrated workflow that combines AI-driven modeling with physics-based refinement. This means that, even when no structural templates are available, we can still deliver high-confidence models.
Ab-initio Small Protein Modeling
When no homologous templates exist, we employ ab-initio prediction, folding proteins directly from sequence. In this way, we capture novel structures that traditional comparative modeling cannot resolve. We use state-of-the-art algorithms such as Rosetta and AlphaFold-derived pipelines.
Molecular Dynamics for Small Protein Stability
Next, we refine the predicted models using molecular dynamics simulations, ensuring that the structures are stable in biologically relevant environments. As a result, our clients receive models that reflect realistic conformations.
Docking and Interaction Studies of Small Proteins
Furthermore, we perform docking and interaction analysis, exploring how small proteins engage with receptors, antibodies, or membranes. This not only highlights functional binding sites, but also helps guide therapeutic design.
