Biocatalysis is all about using enzymes to make stuff, and it's a big deal for many industries. One cool way scientists are making it even better is by looking back in time. They use something called ancestral sequence reconstruction (ASR) to figure out what ancient enzymes might have looked like. This helps them create super-stable enzymes and even tools to make new ones. Plus, it gives insights into how enzymes work in ways that current ones can't.
Think of it like this: if you want to build a better car, you might look at old cars to see what worked great. That's what ASR does for enzymes. It can make them more heat-resistant, help them do more things, and make them better at specific tasks. It's like a treasure map leading to super enzymes!
We're in a golden age of biocatalysis, with lots of useful enzymes already made. ASR is just one more amazing tool scientists have to keep making things even better.
