Summary:
When bacteria lose genes needed to make enzymes for important chemical reactions, defeat isnt inevitable. Sometimes other enzymes will take on new roles to patch together a work-around chain of reactions that does the job. Bacteria that can adapt in this way are more likely to survive when living conditions change, passing along these new tricks to their descendants. So studying these biochemical gymnastics is helping scientists to understand how evolution works on a molecular level.
"'Promiscuous' Enzymes Switch Jobs" is from the September 3, 2016 issue of Science News.
