Enzymes in our bodies, in other animals and in plants and microbes are adept at attaching one carbon to another. But none of those enzymes, so far as we know, have ever bothered to attach a carbon to a silicon. They coaxed a natural protein called cytochrome c into joining a silicon and oxygen. Cytochrome c doesn’t even usually make bonds, which is to say it’s not a natural enzyme. Here’s a bond not found in nature, but a natural protein is happy to do it given the right environment,” says Arnold.
