The electronic structure and dipole moment of charybdotoxin, a scorpion venom peptide with K+ channel blocking activity [PDF]
Computational and Theoretical Chemistry 963 (2011) 384-393, 2010 The electronic structure of charybdotoxin (ChTX), a scorpion venom peptide that is known to act as a potassium channel blocker, is investigated with the aid of quantum mechanical calculations. The dipole moment vector (145 D) of ChTX can be stirred by the full length KcsA potassium channel's macrodipole (403 D) thereby assuming the proper orientation ...

A Novel Insecticidal Spider Peptide that Affects the Mammalian Voltage-Gated Ion Channel hKv1.5
Frontiers in Pharmacology, 2021 Spider venoms include various peptide toxins that modify the ion currents, mainly of excitable insect cells. Consequently, scientific research on spider venoms has revealed a broad range of peptide toxins with different pharmacological properties, even ...

Molecular Spiders on the Plane [PDF]
Phys. Rev. E 85, 061927 (2012), 2012 Synthetic bio-molecular spiders with "legs" made of single-stranded segments of DNA can move on a surface covered by single-stranded segments of DNA called substrates when the substrate DNA is complementary to the leg DNA. If the motion of a spider does not affect the substrates, the spider behaves asymptotically as a random walk.

Revealing the Venomous Secrets of the Spider’s Web
Journal of Proteome Research, 2020 Orb-weaving spiders use a highly strong, sticky and elastic web to catch their prey. These web properties alone would be enough for the entrapment of prey; however, these spiders may be hiding venomous secrets in the web, which current research is revealing. Here, we provide strong proteotranscriptomic evidence for the presence of toxin/neurotoxin-like

Spider Venoms: Biochemical Aspects [PDF]
American Zoologist, 1969 SYNOPSIS. The venoms of spiders are quite complex and contain an array of biologically active components. The majority of studies on the biochemical aspects of these venoms have utilized four species: Phoneutria fera, Lycosa erythrognatha, Atrax robustus , and Latrodectus mactans .

Brown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
Toxins, 2011 Venomous animals use their venoms as tools for defense or predation. These venoms are complex mixtures, mainly enriched of proteic toxins or peptides with several, and different, biological activities.

Molecular Spiders in One Dimension [PDF]
Journal of Statistical Mechanics P08027 (2007), 2007 Molecular spiders are synthetic bio-molecular systems which have "legs" made of short single-stranded segments of DNA. Spiders move on a surface covered with single-stranded DNA segments complementary to legs. Different mappings are established between various models of spiders and simple exclusion processes.
