Researchers have used AI to design enzymes from scratch that cut up other proteins, the article reports.

Nature describes the de novo design of working cysteine proteases.

The work comes from a University of Washington institute led by Nobel laureate David Baker.

The enzymes act as molecular scissors aimed at disease-linked proteins, GeekWire reports.

Unlike most drugs, which block a harmful protein, these destroy the target outright.

Lab experiments confirmed the AI designs fold correctly and actually cut.

The same AI pipeline could in principle be aimed at different targets.

Specificity and delivery remain the central hurdles before any therapy.
