# Google DeepMind and EMBL-EBI: AlphaFold Protein Structure Database precomputed structure access

Researchers can use precomputed structure predictions, then decide what experimental validation is required.

Function: Engineering design. Patterns: Continuous decisioning. Evidence: verified.

Freshness: current. Reviewed: 2026-08-23. Updated: 2026-08-22.


Source quality: 1 peer reviewed, 1 primary; publication outcomes are verified.

## Before

1. **Structural biologist** — Search the much smaller experimental structure corpus or initiate a bespoke structure-determination project. (control: Experimental feasibility)
2. **Research team** — Wait for a structure before pursuing structure-informed hypotheses. (control: Scientific judgment)

## After

1. **AlphaFold DB** — Serves a precomputed predicted structure and confidence metrics for a queried protein sequence. (control: Prediction confidence and coverage)
2. **Researcher** — Uses predictions to form hypotheses, design experiments, or solve structures, validating consequential uses. (control: Human scientific validation)

## Decision rights

AlphaFold supplies a prediction; scientists decide whether confidence is sufficient and what experimental validation is required.

## Exception path

Low-confidence regions, multimers, nonstandard sequences, and consequential claims require alternative methods or experiments.

## Outcomes

- **Protein sequences with openly accessible predicted structures** (verified): Approximately 200,000 PDB structures representing about 60,000 unique sequences → More than 214 million predicted structures, covering nearly the full UniProt database. Coverage is not equivalent to experimental accuracy or research impact; predictions have confidence limits and do not replace validation for many uses.

## Executive lesson

The transformation is infrastructural: a once-scarce intermediate artifact became available on demand, shifting scientists from acquisition toward interpretation and validation.

## Anti-pattern

Treating a predicted structure as experimentally confirmed or counting database entries as discoveries.

## Questions for leaders

- Which intermediate artifact could become shared AI infrastructure?
- How will users see uncertainty at the point of use?
