WebN-terminal sequencing of peptides was done on an ABI 473A Protein Sequencer. Cleavage of the oligosaccharides from the peptides was done with recombinant N-glycanase … Web1. Hydrolysis - This is generally a problem in peptides containing Asp (D) in the sequence, which is susceptible to dehydration to form a cyclic imide intermediate. If the sequence contains Asp-Pro (D-P), the acid catalyzed formation of cyclic imide intermediate can result to cleavage of the peptide chain.

Webmodification of the product peptide; reaction with the linker cation gives irreversible reattachment of the peptide to the resin [3]. With methionine, further reaction can occur giving rise to homoserine and fragmentation of the peptide chain. By adding scavengers to the cleavage mixture, these side reactions can be largely suppressed. WebPeptide synthesis is characterized as the formation of a peptide bond between two amino acids.
