ConoServer, a database for conopeptide sequences and structures [PDF]

open access: yesBioinformatics, 2007
Abstract Summary: ConoServer is a new database dedicated to conopeptides, a large family of peptides found in the venom of marine snails of the genus Conus. These peptides have an exceptional diversity of sequences and chemical modifications and their ability to block ion channels makes them important as drug leads and tools for ...

Engineered biosynthesis of cyclotides

open access: yesNew Zealand Journal of Botany, Volume 58, Issue 4, Page 358-377, December 2020., 2020
ABSTRACT A system based on cyanobacterial split inteins, SICLOPPs (Split Intein Circular Ligation of Proteins and Peptides), has been used to synthesise a small natively cyclic plant protein, kalata B1, and cyclised versions of the natively linear therapeutic peptides ziconotide and leconotide.

Stabilization of α-conotoxin AuIB: Influences of disulfide connectivity and backbone cyclization [PDF]

open access: yes, 2011
alpha-Conotoxins are peptides isolated from the venom ducts of cone snails that target nicotinic acetylcholine receptors (nAChRs). They are valuable pharmacological tools and have potential applications for treating a range of conditions in humans ...

Calcium channels controlling acetylcholine release from preganglionic nerve terminals in rat autonomic ganglia [PDF]

open access: yes, 1999
Little is known about the nature of the calcium channels controlling neurotransmitter release from preganglionic parasympathetic nerve fibres. In the present study, the effects of selective calcium channel antagonists and amiloride were investigated on ...

The Tetrodotoxin Receptor of Voltage-Gated Sodium Channels—Perspectives from Interactions with μ-Conotoxins

open access: yesMarine Drugs, 2010
Neurotoxin receptor site 1, in the outer vestibule of the conducting pore of voltage-gated sodium channels (VGSCs), was first functionally defined by its ability to bind the guanidinium-containing agents, tetrodotoxin (TTX) and saxitoxin (STX ...

Evolution: Fangtastic Venoms Underpin Parasitic Mimicry [PDF]

open access: yes, 2017
Venomous teeth are rare in fishes, which typically utilise spines for defence. A new study reveals the evolutionary origins of fangs and venom in the Nemophini blennies and shows that, in contrast to snakes and lizards, the fangs pre-date the ...

The Evolution of Fangs, Venom, and Mimicry Systems in Blenny Fishes [PDF]

open access: yes, 2017
Venom systems have evolved on multiple occasions across the animal kingdom, and they can act as key adaptations to protect animals from predators. Consequently, venomous animals serve as models for a rich source of mimicry types, as non-venomous ...
