Interaction of a synthetic antimicrobial peptide with model membrane by fluorescence spectroscopy
(Springer, 2013-12-01)
Static and time-resolved fluorescence of tryptophan and ortho-aminobenzoic acid was used to investigate the interaction of the synthetic antimicrobial peptide L1A (IDGLKAIWKKVADLLKNT-NH2) with POPC and POPC:POPG. N-acetylated ...
Probing the binding of the coumarin drugs using peptide fragments of DNA gyrase B protein
(2005-05-01)
Bacterial DNA gyrase, has been identified as the target of several antibacterial agents, including the coumarin drugs. The coumarins inhibit the gyrase action by competitive binding to the ATP-binding site of DNA gyrase B ...

Development of an operational substrate for ZapA, a metalloprotease secreted by the bacterium Proteus mirabilis
(Associação Brasileira de Divulgação Científica (ABRADIC), 2000-07-01)
The protease ZapA, secreted by Proteus mirabilis, has been considered to be a virulence factor of this opportunistic bacterium. The control of its expression requires the use of an appropriate methodology, which until now ...
Fluorescence spectroscopy of small peptides interacting with microheterogeneous micelles
(ELSEVIER SCIENCE BV, 2010)
Many peptides containing tryptophan have therapeutic uses and can be studied by their fluorescent properties. The biological activity of these peptides involves interactions with many cellular components and micelles can ...
