How to Use DLKcat Kcat Prediction
Commercially Available Online Web Server
Use DLKcat Kcat Prediction online for enzyme turnover number prediction and substrate-panel screening.
DLKcat is a deep learning model for predicting enzyme turnover numbers from protein sequence and substrate chemistry. The Nature Catalysis paper positions it as a response to the scarcity and noise of experimental kcat data, enabling high-throughput estimation of catalytic rates across enzymes and compounds that would be impractical to assay exhaustively.
On Neurosnap, researchers provide one enzyme Input Sequence and a panel of Input Molecules to compare substrate-specific turnover estimates in a single run. The workflow is useful for enzyme prioritization, substrate screening, mutation campaigns, and early metabolic-model parameterization when experimental kinetics are incomplete.
How DLKcat Kcat Prediction Works
The published work shows that DLKcat can recover meaningful kcat trends from sequence and substrate representations, capture rate changes caused by enzyme mutation, and highlight residues with strong influence on catalytic turnover. The authors also used predicted values to parameterize enzyme-constrained genome-scale metabolic models across more than 300 yeast species, demonstrating that the method is useful well beyond one-off enzyme scoring.
On Neurosnap, DLKcat is best used as a ranking tool rather than a substitute for biochemical assays. Compare predicted turnover numbers across substrate panels or sequence variants, then use the ranking to decide which enzyme-substrate pairs deserve purification, steady-state kinetics, or deeper structural analysis.
What is Neurosnap?
Neurosnap is the leading platform for bioinformatics and computational science focused on expanding access to powerful modeling and simulation tools.

Advancing Discovery with DLKcat Kcat Prediction on Neurosnap
Using DLKcat Kcat Prediction on Neurosnap could drastically accelerate enzyme turnover number prediction across substrate panels from protein sequence and small-molecule input.
- Panel-based screening: One enzyme sequence can be evaluated against many candidate substrates in a single run, which matches early catalytic profiling workflows.
- Kcat-specific focus: DLKcat is tuned for turnover number estimation rather than broader enzyme-property prediction, making it especially relevant to catalytic prioritization.
- Mutation sensitivity: The paper shows the model can capture
kcatchanges caused by sequence variation, which is valuable in enzyme engineering campaigns. - Systems-biology relevance: Predicted values can inform downstream metabolic modeling as well as lab-scale substrate and variant selection.
