Salk scientists add new bond to protein engineering toolbox

Proteins are the workhorses of cells, adopting conformations that allow them to set off chemical reactions, send signals and transport materials. But when a scientist is designing a new drug, trying to visualize the processes inside cells, or probe how molecules interact with each other, they can't always find a protein that will do the job they want. Instead, they often engineer their own novel proteins to use in experiments, either from scratch or by altering existing molecules.
