Applying SPPS to Lichenicidin Synthesis

The successful synthesis of lichenicidin via solid-phase peptide synthesis involves several critical considerations. Given that lichenicidin is a two-peptide lantibiotic, SPPS would likely be employed to synthesize each peptide component individually. Researchers have explored solid-phase peptide synthesis for other lantibiotics, such as lacticin 481, demonstrating its feasibility for this class of compounds (Piscotta et al., 2015).

The synthesis of the linear precursor peptide of lichenicidin using SPPS is a critical initial step. Following the assembly of the linear sequence on the resin, the peptide is cleaved from the solid support.Production of the novel two-peptide lantibiotic lichenicidin ... The subsequent steps would then focus on replicating the complex post-translational modifications (PTMs) that occur naturally. While SPPS excels at assembling the linear polypeptide chain, mimicking the intricate PTM machinery of ribosomal peptide synthesis chemically remains a significant challenge (Karbalaei-Heidari et al., 2020).2023年1月31日—What issolid phase peptide synthesisand why was it developed?
