Understanding the Foundation: SPPS and Lanthipeptides
Solid Phase Peptide Synthesis (SPPS) has become the gold standard for creating peptides by assembling amino acids in a stepwise fashion on a resin support. When synthesizing these compounds, the primary goal is to ensure high purity and yield. Unlike linear sequences, lanthipeptides present unique challenges due to their characteristic thioether cross-links, known as lanthionine or methyllanthionine rings.
From my experience reviewing laboratory protocols, SPPS allows for the use of a large excess of reagents, which is crucial for driving coupling reactions to completion. This efficiency is vital when working with complex molecules like SapB, which is essential for aerial mycelium formation in *Streptomyces*.
