N-[(2S)-4-[(2S)-1-decanoylpyrrolidin-2-yl]-2-(1-hydroxyethyl)-4-oxobutanoyl]-L-alanyl-N1-[(2S)-1-oxopropan-2-yl]-L-aspartamide | i.e. decanoyl-PTANA-aldehyde, inhibition by the synthetic substrate-based peptide aldehyde, overview. The length of the core lipopeptide can be reduced by removing several amino acids from both termini. Conversion of this peptide to an aldehyde. The signal peptide consists of three domains, a positively charged N-terminal domain, n-region, a hydrophobic middle domain, which contains usually 7-15 amino acids forming an alpha-helix, h-region, and a C-terminal domain, c-region, which is responsible for substrate recognition | Staphylococcus aureus |
