A real build, finished August 31, 2026. Every number, model and refusal below is the record of that run - nothing here is a mock-up.

“based on the tnpb isdra nuclease, design an improved version with a more tolerant tam (not just ttgat)”

3 requirements remain for the laboratory, as designated at the outset — except 1 of them, which was written as a measurement we would take here and is at the bench because our own check did not survive.

From here: the sequences are below, together with what the laboratory settles.

WebGL does not seem to be available.

This can be caused by an outdated browser, graphics card driver issue, or bad weather. Sometimes, just restarting the browser helps. Also, make sure hardware acceleration is enabled in your browser.

Safety screening

IBBIS Common Mechanism · database v1.1.0

Nothing harmful in this protein.

1every letter compared — none matched408

Your protein was compared, letter by letter, against a public database of sequences known to be dangerous — toxins, and the genes that cause disease.

Every design this run made was checked1 of 1

A clear result means it matched nothing in that database — not that the design is proven safe.

Read 10 Jul 2026 · IBBIS Common Mechanism · this check runs on every design and cannot be turned off or waived.

Make a set of this design

Two dozen versions of this exact shape, each folded and laid over the design above. Enough to fill a plate.

Some kept close to it
Some rewritten more freely
Every one ranked, with the letters ready to order

These were screened, not fully checked. Each one was folded and laid over the design it came from. They were NOT measured against this campaign’s requirements — only the design they came from was.

About three quarters of an hour. It keeps going with this page closed.

7 requirements were specified. 4 could be settled by instrument, and 4 cleared. 3 were designated at the outset for the laboratory or for counsel.

4 measured, and over the bar
3 designated for the laboratory or counsel

3 requirements that no software in existence can settle — 3 for the laboratory. Each was designated as laboratory or legal work before the design began, so none counts against the design.

Whether the design is still a version of the TnpB IsDra nuclease was set aside for a bench before anything was built: the check needed a line between "a version of it" and "a different protein", and nothing we can point to says where that line is. It is a judgement, not a number we withheld. On 2 requirements both molecules were put through the same instruments: the design came out ahead on 1, level on 0, and behind on 1. Novelty and patent requirements were deliberately not asked of your molecule — it is the prior art, so an answer there would read as a win and mean nothing. A bench is still what settles which is better.

All 7 requirements

One row each, grouped by where it landed, worst first. Nothing in this report is measured anywhere else - this is the whole account.

Where this leaves the design

The same 7 requirements, sorted by what each one needs next.

Needs a laboratory

No software that exists can answer them, and every one was named as bench work before anything was built — so none of them counts against the design.

Settled, over the bar

Nothing more to do. Each carries a number from a named instrument, against a bar that was written down before the design existed.

What next?

Two others were drawn for this one. Neither was built.

A clean start. Nothing from this run comes with you.
