Looking beyond the sequence: New Purdue tool reveals hidden patterns in protein evolution

Proteins are the tiny machines that power life, carrying out nearly every task inside living cells. While scientists have long studied the genetic code that builds these proteins, a team at Purdue University has developed a new way to see something that traditional approaches often miss: how evolution shapes proteins in three dimensions.
