Macrolactin N, a new peptide deformylase inhibitor produced by Bacillus subtilis
摘要:
A new 24-membered ring lactone, macrolactin N, was isolated from a culture broth of Bacillus subtilis and its structure was established by various spectral analysis. Macrolactin N inhibited Staphylococcus aureus peptide deformylase with an IC50 value of 7.5 mu M and also showed antibacterial activity against Escherichia coli and S. aureus. (c) 2006 Elsevier Ltd.

N-to-C peptide ligation. Our model unites prebiotic aminonitrile synthesis and biological α-peptides, suggesting that short N-acyl peptide nitriles were plausible substrates during early evolution.Prebiotic peptide formation is achieved through chemoselective, high-yielding ligation of α-aminonitriles in water, showing selectivity for α-peptide coupling and tolerance of all proteinogenic amino acid residues

In eubacteria and eukaryotic organelles N-terminal methionine excision requires the sequential action of two activities, a peptide deformylase (PDF), which systematically removes the N-formyl group present on all nascent polypeptides and methionine aminopeptidase (MAP), which exscinds methionine specifically and depends on the previous removal of the N-formyl group. In Trypanosoma cruzi two genes encoding bacterial PDF homologues have been identified and referred to as TcPDF-1 and TcPDF-2. Here we report the biochemical characterization of a truncated soluble version of TcPDF-1 lacking the hydrophobic N-terminal domain that is active with the bacterial PDF substrate formyl-methionyl-alanyl-serine but, in contrast to other PDFs, is not inhibited by actinonin. The enzyme is strongly activated by Cu2+ and inhibited by Ni2+. Our results show that T. cruzi PDF exhibits unique features thus providing a new avenue for the design of potential inhibitors for use in the treatment of diseases caused by trypanosomatid parasites.
