We investigated how #enzymes in the #nonribosomal #biosynthesis of life-saving #peptide #antibiotics can be engineered.
Assuming that #promiscuity serves as a springboard for #evolution, we measured the specificity profiles of hundreds of mutants. The results revealed remarkable shifts in substrate specificity in multiple directions, highlighting the evolutionary potential of these enzymes and leading the way for engineering antibiotic biosynthesis.
