What is Peptide Structure Prediction?
Peptide structure prediction refers to the process of predicting the three-dimensional structure of a peptide or a short peptide fragment. Peptides are short chains of amino acids that play crucial roles in various biological processes, such as signaling, regulation, and molecular recognition. Accurate prediction of peptide structure is essential for understanding their function and designing therapeutic agents that can specifically target them. Peptide structure prediction methods utilize computational algorithms and modeling techniques to generate models of the peptide's spatial arrangement, including its secondary structure (alpha-helices, beta-sheets) and tertiary structure (overall three-dimensional folding). These predictions are based on various factors, including the peptide sequence, physicochemical properties, and statistical analyses of known protein structures. Successful peptide structure prediction can provide valuable insights into peptide function, and interactions, and help in drug discovery and design processes.

We offer molecular docking simulations to investigate the interaction between your peptide and potential binding partners. This enables you to evaluate the binding affinity and specificity of the peptide, facilitating rational drug design and optimization.
- Visualization and Analysis
We can provide toolkits and services for visualizing and analyzing predicted peptide or protein structures.
Our Techniques
- Ab Initio Methods: Our service employs ab initio methods. These methods are particularly useful for small peptides and when no prior structural information is available. For ab initio methods, we rely on software such as Rosetta and CNS. These programs use algorithms based on physics and statistical analysis to predict the peptide's 3D structure from scratch.
- Comparative Modeling: We use comparative modeling techniques to predict the structure based on known homologous protein structures. This approach is suitable when a structurally similar protein is available as a template. we make use of software packages like MODELLER, SWISS-MODEL, and I-TASSER. These tools use sequence alignment algorithms to identify suitable template structures and generate the predicted 3D structure.
- Molecular Dynamics Simulation: We use stretching dynamics simulation, copy exchange dynamics simulation and other methods to study the structure of peptides. The sampling space of peptide conformations can be increased through molecular dynamics simulations. The movement of a peptide over time allows us to understand its flexibility and stability. To model the dynamics of peptides, we use software such as GROMACS, AMBER, and NAMD.
