Silent PAM Destroyer
Remove unwanted PAMs with silent mutations to lock in your edit.
Design silent mutations that break PAMs and stop re-cutting while preserving protein sequence inside Omnis Helix, the Genome IDE for editing.
Tool definition
What the tool is
The Silent PAM Destroyer finds codon-safe substitutions that disrupt PAMs without changing the amino acid sequence.
Decision pressure
Why scientists care
After HDR or Prime edits, remaining PAMs can trigger re-cutting and mixed populations.
Genome IDE fit
How the Genome IDE helps
Codon table-aware swaps that break PAM motifs while keeping protein sequence
Scoring model
How the algorithm works
We evaluate all codon substitutions that disrupt the PAM motif, ranking by synonymous preference and model implied mRNA stability.
Evaluation path
Try it in the Genome IDE
Select the PAM to disable, review suggested silent swaps, and apply the edit to your design.
Questions
FAQ
Does this alter amino acid sequence?
No—suggestions are synonymous unless you explicitly allow conservative substitutions.
Can I chain this with HDR donors?
Yes—Helix can embed the silent PAM destroyer into your HDR template automatically.
Do you support non-coding regions?
We surface motif-safe swaps for non-coding contexts where applicable.
