Lasso peptides: A focus on therapeutic index

Area of Science:

• Biochemistry and Molecular Biology
• Pharmacology
• Drug Discovery

Background:

• Lasso peptides are a class of ribosomally synthesized and post-translationally modified peptides (RiPPs).
• They possess a unique lasso structure characterized by a macrolactam ring with a threaded tail, conferring exceptional stability.
• This structural motif underpins their diverse biological activities and therapeutic potential.

Purpose of the Study:

• To review the structural diversity of lasso peptides.
