thioester ligation biosynthesis modification

Overview

Thioester bonds are high-energy linkages between thiols and carboxyl groups, important in peptide biosynthesis.

Types

  • Intein-mediated: Protein splicing through thioester intermediates
  • NGL (Native Chemical Ligation): Cys-mediated peptide joining
  • Complement C3/C4: Thioester-mediated opsonization

Biological Significance

Thioester intermediates enable native chemical ligation for synthetic protein construction. Complement thioester bonds are essential for innate immunity.
