Lasso peptides. Bioactive peptides from Actinobacteria and Proteobacteria

Archive ouverte | Zirah, Séverine | CCSD

Certain bacteria produce 16/21-residue peptides that share a compact lasso-folded structure involving a 8/9-residue ring resulting from a lactame bond between the N-terminus and the carboxylic group of an Asp/Glu residue, crossed ...

The iron-siderophore transporter FhuA is the receptor for the antimicrobial peptide microcin J25: role of the microcin Val11-Pro16 beta-hairpin region in the recognition mechanism.

Archive ouverte | Destoumieux-Garzón, Delphine | CCSD

International audience. The role of the outer-membrane iron transporter FhuA as a potential receptor for the antimicrobial peptide MccJ25 (microcin J25) was studied through a series of in vivo and in vitro experimen...

Isolation and structural characterization of capistruin, a lasso peptide predicted from the genome sequence of Burkholderia thailandensis E264.

Archive ouverte | Knappe, Thomas A | CCSD

International audience. Lasso peptides are a structurally unique class of bioactive peptides characterized by a knotted arrangement, where the C-terminus threads through an N-terminal macrolactam ring. Although ribo...
