Frequently asked questions

ProteinIQ supports the computational stages of enzyme engineering in one connected workspace. Researchers can annotate sequences, inspect substrate context, predict turnover or stability, model structures, and score variants while keeping every output tied to the enzyme candidate it describes. Begin with an enzyme sequence or structure and select a workflow for activity, stability, mutation, or substrate analysis. ProteinIQ returns the source tables, structures, scores, and files needed to compare candidates before experimental enzyme assays.

ProteinIQ supports enzyme engineering workflows for enzyme annotation, substrate context review, activity prediction, kcat-style scoring, mutation and stability screening, structure modeling, and inhibitor or substrate triage. The platform keeps upstream tool outputs available so enzyme decisions can be reviewed rather than treated as black-box results.

ProteinIQ enzyme tools commonly accept enzyme FASTA sequences, PDB structures, substrate SMILES, inhibitor libraries, mutation lists, and tabular inputs depending on the upstream method. Each workflow keeps the accepted input type tied to the tool that generates the activity, stability, or structure output.

Yes. ProteinIQ can compare enzyme variants with mutation, stability, solubility, structure, and activity-related outputs depending on the selected tools. The results are preserved as tables, structure files, logs, and other artifacts so candidate variants can be compared side by side.

ProteinIQ can run enzyme activity and kcat-oriented prediction tools when the required sequence, structure, or substrate inputs are available. These outputs are computational prioritization signals, so ProteinIQ presents the scores and input context for review rather than treating them as measured kinetic constants.

Yes. ProteinIQ can connect enzyme sequences or structures to design, mutation scoring, and stability prediction tools that help prioritize variants for testing. The platform keeps the redesigned sequences, mutation tables, stability scores, and structure evidence tied to the original enzyme context.

Yes. When an enzyme workflow includes compound context, ProteinIQ can help review substrate or inhibitor candidates with structure, docking, property, and ADMET-style evidence depending on the tools selected. These results support triage and experimental planning rather than replacing biochemical validation.

No. ProteinIQ provides computational enzyme engineering and prioritization evidence. Enzyme kinetics, activity, specificity, stability, expression, and substrate-scope claims still require experimental enzyme assays before they should be treated as validated results.

Yes. ProteinIQ enzyme workflows can export CSV score tables, sequence files, predicted or prepared structures, mutation outputs, docking or compound tables, logs, and upstream result artifacts depending on the tool. Exported files preserve the evidence needed for review outside ProteinIQ.

Start in ProteinIQ with an enzyme sequence or structure and choose either a workflow template or a specific tool for activity prediction, stability review, structure modeling, or compound triage. Running a small test input first is the best way to confirm formatting before scaling to larger variant sets.
