MtoZ Biolabs employs an advanced computational simulation platform and has launched the molecular docking service which enables systematic analysis of binding modes, interaction features, and potential key sites between active peptides and various receptor molecules. This service is widely applied in active peptide screening, structural optimization, and mechanism studies, providing a reliable data foundation for functional peptide development, targeted design, and activity prediction.
What Is Molecular Docking?
Molecular docking is a computational technique used to predict the optimal binding modes between molecules and to analyze their interaction relationships. Its principle is to simulate possible ligand binding conformations on a receptor through spatial matching and energy scoring, and to evaluate binding stability and affinity. As an important tool in structural biology and drug design, molecular docking can rapidly reveal potential interaction patterns between peptides and proteins, receptors, or small molecules. For active peptide research, it helps identify key binding sites, predict functional mechanisms, and support functional peptide screening and peptide drug sequence optimization.
