Ficain

Ficain is a special kind of protein that is really good at cutting up other proteins. It's like a pair of scissors, but for really tiny things.

Scientists use ficain to help them study different proteins and figure out what they do. They can use it to cut proteins into smaller pieces so they can study them more easily.

It's also used in industries like food and cosmetics to help break down proteins so they can be used in different products.

Overall, ficain is a very useful tool for scientists and industries that need to work with proteins. It's kind of like having a tiny, super-powered pair of scissors.
