The Acinetobacter outer membrane contains multiple specific channels for carbapenem β-lactams as revealed by kinetic characterization analyses of imipenem permeation into Acinetobacter baylyi cells
(American Society for Microbiology, 2017-03)
The number and type of outer membrane (OM) channels responsible for carbapenem uptake in Acinetobacter are still not well defined. Here, we addressed these questions by using Acinetobacter baylyi as a model species and a ...
Molecular determinants of binding of a wasp toxin (PMTXs) and its analogs in the Na+ channels proteins
(Elsevier B.V., 2000-05-05)
The structural specificity of alpha-PMTX, a novel peptide toxin derived from wasp venom has been studied on the neuromuscular synapse in the walking leg of the lobster. alpha-PMTX is known to induce repetitive action ...

Crystal structure of neurotoxin Ts1 from Tityus serrulatus provides insights into the specificity and toxicity of scorpion toxins
(Academic Press LtdLondonInglaterra, 1999)
Purification and characterization of Ts15, the first member of a new alpha-KTX subfamily from the venom of the Brazilian scorpion Tityus serrulatus
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
Voltage-gated potassium channel toxins (KTxs) are basic short chain peptides comprising 23-43 amino acid residues that can be cross-linked by 3 or 4 disulfide bridges. KTxs are classified into four large families: alpha-, ...
Structural and functional characterization of toxic peptides purified from the venom of the Colombian scorpion Tityus macrochirus
(2019)
The soluble venom of the scorpion Tityus macrochirus was separated by chromatographic procedures and three homogeneous peptides were obtained and their primary structures were determined. They were called: Tma1-Tma3, from ...
Tx2-6, uma toxina da aranha Phoneutria nigriventer que modifica os canais de Na+ sensíveis à voltagem
(Universidade Federal de Minas GeraisUFMG, 1999-06-11)
Many organisms produce polypeptides with toxic activity against other organisms. The voltage-gated sodium channels are the main targets of many toxins studied so far. Two specific binding sites of polypeptide toxins have ...
