kcat
kcat provides a first-pass sequence-based signal for enzyme turnover potential.
What It Does
The oracle helps compare enzymes and variants when catalytic throughput is a key design or screening objective.
Why It Matters
Enzyme campaigns often need to decide which variants deserve kinetic characterization. A turnover-oriented signal can help rank candidates before expensive assays.
Intended Use
Use kcat for early enzyme triage, variant ranking, and prioritization of candidates for kinetic measurement.
Limitations
kcat is substrate-specific and condition-specific. Sequence alone cannot capture substrate identity, cofactors, pH, temperature, expression quality, or assay format. Treat predictions as hypotheses for experimental prioritization.
Try kcat
Run predictions with this model through the Synthyra platform.
