How to make a random protein with the same composition

Paste a protein sequence to sample from.
Set the length and number of sequences to make.
Click Generate. Each residue is drawn at random from your sequence, so the composition is about the same.

Frequently asked questions

How is this different from Shuffle Protein?

Shuffle keeps the exact counts and length. Sampling draws with replacement, so the length can be anything and the counts vary a little.

Is my sequence uploaded?

No. Everything runs in your browser, so your sequences never leave your device.
