Protein Structure Modeling - Neorabio
Neorabio provides protein structure modeling services for research teams that require reliable 3D structural information to support functional interpretation, drug design, and molecular mechanism studies. The value of computational modeling in structural biology—highlighted early in comparative modeling frameworks such as those discussed by Marti-Renom et al. (2000)—lies in its ability to deliver structural insights when experimental data are incomplete or unavailable. Building on these foundations, Neorabio implements modeling pipelines that emphasize physical plausibility, geometric consistency, and biological interpretability.

About Service

Our structure-modeling approach integrates homology modeling, deep learning–based prediction, and ab initio reconstruction. Deep learning methods, including those underlying AlphaFold, have demonstrated exceptional predictive capability across diverse protein families, as illustrated by Jumper et al. (2021). Neorabio incorporates these advances into a curated workflow that includes alignment processing, template evaluation, refinement of predicted coordinates, and structural validation. This blend of computational strategies, supported by high-performance hardware and well-defined QC criteria, allows us to generate protein models suitable for downstream simulation and design tasks.

Key Advantages

● Hybrid modeling strategy: Combines template-based modeling, deep learning predictions, and ab initio reconstruction where templates are insufficient.
● Geometric and energetic refinement: Minimization and relaxation steps ensure that predicted structures adopt physically reasonable conformations.
● Comprehensive validation: Ramachandran statistics, clash analysis, model confidence scoring, and domain-resolution checks are included.
● Flexible modeling options: Customized strategies for membrane proteins, multi-domain architectures, enzyme active sites, or disordered regions.
● Transparent interpretation: Deliverables include residue-level confidence metrics, alternative conformations, and binding-site annotations when applicable.

Applications

● Structure-based drug design: Binding-site mapping, pocket characterization, and ligand-interaction hypothesis generation.
● Functional annotation: Predicting molecular roles, active residues, or structural motifs.
● Protein engineering: Assessing mutation impacts on stability, folding, or functional domains.
● Mechanistic and structural biology studies: Supporting hypothesis development for conformational changes or regulatory mechanisms.
● Preparation for downstream simulations: Providing optimized coordinates for MD, QM/MM, docking, and free-energy calculations.

Workflow

Submit sequence/structural information → Template search & method selection → Structure modeling → Energy optimization → Structure evaluation → Report delivery

Inquiry Center

Neorabio's modeling specialists work across therapeutic proteins, enzymes, receptors, antibodies, and challenging targets such as membrane proteins and multi-domain architectures. The team evaluates template quality, alignment strategies, model uncertainty, and domain segmentation before model construction begins. Final deliverables include refined structures, confidence analyses, variant-specific models (if needed), and project-tailored annotations. These practices ensure that the resulting 3D structures are both technically rigorous and immediately useful for experimental design, computational follow-up, or hypothesis generation.
