Pathway Edits

  • LANM (lanthipeptide modifying enzyme homolog) activity-tuned expression for Lan dehydration
  • LANB (lanthipeptide biosynthesis protein B) protease expression for leader peptide cleavage
  • LanC-like cyclase expression for lanthionine ring structure formation in yeast
  • ProcA precursor peptide cassette expression with optimized leader sequence
  • Lanthipeptide ABC transporter expression for extracellular cyclic peptide secretion
  • Lan-RG (lanthipeptide regulator/immunity protein) expression for pathway stability
  • Prepeptide processing protease expression for mature cyclic CaSR ligand liberation
