🧬 How to use CatPred Online

Use CatPred online for enzyme kinetic parameter prediction from enzyme sequence and substrate structure.

CatPred is a deep learning framework for predicting in vitro enzyme kinetic parameters from enzyme sequence and substrate or inhibitor structure. The Nature Communications paper expands beyond single-task kcat prediction by covering kcat, Km, and Ki in a unified benchmarked framework with explicit uncertainty estimates.

On Neurosnap, researchers provide one enzyme Input Sequence, one or more Input Molecules, and choose which Parameter to predict. The tool is well suited to enzyme prioritization, substrate panel screening, inhibitor triage, and early assay planning when experimental kinetics are too slow or expensive to measure at scale.

How CatPred Works

CatPred addresses several failure modes common in enzyme-kinetics machine learning: inconsistent curation, poor generalization to dissimilar enzymes, and missing confidence information. The paper evaluates multiple feature representations, including pretrained protein language models and structural features, and reports that language-model representations are especially helpful on out-of-distribution sequences.

A second key contribution is query-specific uncertainty quantification. Instead of returning only a point estimate, CatPred reports total, aleatoric, and epistemic uncertainty so researchers can distinguish apparently strong predictions from predictions that are numerically high but poorly supported by the model.

On Neurosnap, that makes the output table useful for more than rank ordering. Researchers can compare predicted kcat, Km, or Ki values across a substrate or inhibitor set and then down-weight high-uncertainty calls before choosing variants, substrates, or follow-up experiments.

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 CatPred on Neurosnap

Using CatPred on Neurosnap could drastically accelerate enzyme-substrate kinetic prediction with uncertainty-aware ranking of kcat, Km, or Ki.

Study-fit inputs: CatPred combines one enzyme sequence with a substrate or inhibitor panel, which matches common kinetic-screening experiments.
Parameter-specific runs: Choosing kcat, Km, or Ki keeps each run aligned with the exact biochemical question being asked.
Uncertainty-aware interpretation: Total, aleatoric, and epistemic uncertainty estimates help separate confident predictions from fragile ones.
Batch-friendly triage: Large molecule panels can be compared in one place before committing to enzyme assays or inhibitor profiling.
