Protein engineering: Finding the best ligase

Modification of folded proteins at will, within any sequence context, remains an elusive goal. A proteome-wide screening approach has now identified a set of protein ligases that enables conjugation of peptides to almost any protein N terminus, overcoming longstanding limitations in protein engineering.
