How to use PocketXMol | Protein Design Online

Use PocketXMol | Protein Design online for receptor-conditioned peptide generation, inverse folding, and side-chain packing.

PocketXMol | Protein Design is the peptide-focused PocketXMol workflow for designing peptides inside a receptor pocket. It supports de novo linear peptide generation, de novo cyclic peptide generation, inverse folding from a peptide template, and side-chain packing, all within one pocket-conditioned three-dimensional modeling framework.

On Neurosnap, researchers upload an Input Receptor, choose Peptide Design Mode, define the receptor pocket, and optionally provide an Input Peptide Template for template-based workflows. This makes the service useful for exploratory peptide-binder ideation as well as more conservative redesign tasks where a starting peptide scaffold already exists.

How PocketXMol | Protein Design Works

PocketXMol conditions generation directly on local atomic interactions inside the receptor pocket, which is why it can support both sequence-structure creation and structure-guided peptide refinement. In de novo modes, the model samples new peptide backbones and side chains against the selected pocket. In inverse folding and side-chain-packing modes, it instead treats a user-provided peptide structure as partial context and optimizes the peptide representation around that template.

On Neurosnap, Peptide Design Mode defines the workflow, while Peptide Length is the main control for de novo generation. Input Peptide Template becomes relevant for inverse folding and side-chain packing, and the peptide-specific advanced controls influence the expected side-chain size distribution during generation. The same pocket-definition inputs used elsewhere in PocketXMol remain important because the receptor site still determines where the peptide is meant to engage.

Returned peptides are best treated as structurally informed proposals for downstream ranking. Researchers can inspect them for plausible pocket engagement, sequence reasonableness, and follow-up compatibility with folding, docking, or experimental screening.

What is Neurosnap?

Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools. Because many state-of-the-art machine learning systems remain complex to install, configure, and scale, Neurosnap offers a clean, browser-based workspace that removes the burden of infrastructure management, dependency conflicts, and command-line tooling.

Built for biologists, chemists, and cross-disciplinary scientists, the platform enables advanced computational workflows without requiring expertise in software engineering or cloud architecture. Researchers can launch analyses through an intuitive interface, connect programmatically through a comprehensive API, and rely on automated resource management to scale workloads efficiently. By taking care of the underlying compute and operational complexity, Neurosnap allows teams to devote their energy to scientific progress and faster iteration. Security and data protection remain foundational principles, with clear safeguards outlined in our Terms of Use and Privacy Policy to ensure your work stays protected.

Advancing Discovery with PocketXMol | Protein Design on Neurosnap

Using PocketXMol | Protein Design on Neurosnap could drastically accelerate receptor-conditioned peptide proposal generation and template-guided peptide redesign from a target pocket.

Peptide-only interface: The workflow removes irrelevant small-molecule docking and fragment-design inputs, making the peptide-design path easier to use correctly.
Multiple peptide design modes: De novo, cyclic, inverse-folding, and side-chain-packing workflows are available inside one receptor-conditioned service.
Pocket-grounded generation: The receptor pocket remains explicit during design instead of being treated as a downstream filter.
Useful for both ideation and refinement: The same service supports novel peptide generation and template-guided redesign.
