Papaya contains an enzyme called papain, which can break down the tough protein chains found in muscle meat. Because of this, people have used papaya to tenderize meat for thousands of years.

Rubisco articles from across Nature Portfolio Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is a copper-containing enzyme involved in the first major step of carbon fixation. It is the ...

This standard lactase activity was accordingly determined by incubating 2.4 mL of lactose substrate (5.2% [w/v] lactose monohydrate in PME, pH 6.6) with 0.1 mL of enzyme for 10 min at 30 °C. The ...

The physical basis for enzymatic rate accelerations is a subject of great fundamental interest and of direct relevance to areas that include the de novo design of green catalysts and the pursuit of ...
