Motifs in the C-terminal region of the Penicillium chrysogenum ACV synthetase are essential for valine epimerization and processivity of tripeptide formation
(2012)
The first step in the penicillin biosynthetic pathway is the non-ribosomal condensation of l-α-aminoadipic acid, l-cysteine and l-valine into the tripeptide δ-(l-α-aminoadipyl)-l-cysteinyl-d-valine (ACV). This reaction is ...
Effect of a highly concentrated lipopeptide extract of Bacillus subtilis on fungal and bacterial cells
(SPRINGER, 2008)
Lipopeptides produced by Bacillus subtilis are known for their high antifungal activity. The aim of this paper is to show that at high concentration they can damage the surface ultra-structure of bacterial cells. A lipopeptide ...
Genetic and functional analysis of the biosynthesis of a non-ribosomal peptide siderophore in burkholderia xenovorans lb400
(2016)
B. xenovorans LB400 is a model bacterium for the study of the metabolism of aromatic compounds. The aim of this study was the genomic and functional characterization of a nonribosomal peptide synthetase containing gene ...
Antimicrobial Cyanopeptide Action on Bacterial Cells Observed with Atomic Force Microscopy
(Bentham Science Publ LtdSharjahEmirados Árabes Unidos, 2013)
Non-ribosomal peptides produced by Brazilian cyanobacterial isolates with antimicrobial activity
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2011)
Cyanobacterial strains isolated from terrestrial and freshwater habitats in Brazil were evaluated for their antimicrobial and siderophore activities. Metabolites of fifty isolates were extracted from the supernatant culture ...
The β1 adrenergic effects of antibodies against the C-terminal end of the ribosomal P2β protein of Trypanosoma cruzi associate with a specific pattern of epitope recognition
(Wiley Blackwell Publishing, Inc, 2005-10)
BALB/c mice immunized with recombinant Trypanosoma cruzi ribosomal P2β protein (TcP2β) develop a strong and specific antibody response against its 13 residue-long C-terminal epitope (peptide R13: EEEDDDMGFGLFD) that has a ...
Atrial natriuretic peptide attenuates endoplasmic reticulum stress in experimental acute pancreatitis
(Elsevier Science, 2019-02)
Increasing evidence shows that the endoplasmic reticulum (ER) stress is an early event that injures pancreatic acinar cells and contributes to the pathogenesis of acute pancreatitis. In the present work we sought to establish ...
