Chemists shows hemoprotein catalysis is way more complicated than we thought

Sometimes, serendipity—or just plain luck—still plays a pivotal role in scientific discovery. Recently, a team of chemists was experimenting with using a biocatalytic process to trigger a cyclopropanation reaction, which yields intricate molecular structures used in various drugs and other natural processes, when something unusual happened: A beaker of liquid that should have turned muddy red turned bright green instead.
