Cytotoxins (CTs) are three-finger membrane-active toxins present mainly in cobra venom. Our analysis of the available CT amino acid sequences, literature data on their membrane activity, and conformational equilibria in aqueous solution and detergent

In aqueous solutions, cobra cytotoxins (CTX), three-finger folded proteins, exhibit conformational equilibrium between conformers with either cis or trans peptide bonds in the N-terminal loop (loop-I). The equilibrium is shifted to the cis form in to

Cobra cytotoxins (CTs) belong to the three-fingered protein family and possess membrane activity. Here, we studied cytotoxin 13 from Naja naja cobra venom (CT13Nn). For the first time, a spatial model of CT13Nn with both “water” and “membrane

Cobra cytotoxins (CTs), the three-fingered proteins, feature high amino acid sequence homology in the beta-strands and variations in the loop regions. We selected a pair of cytotoxins from Naja kaouthia crude venom to clarify the sequence-structure r

For many peripheral membrane-binding polypeptides(MBPs), especially β-structural ones, the precise molecular mechanisms of membrane insertion remain unclear. In most cases, only the terminal water-soluble and membrane-bound states have been elucidat

Antibacterial activity of the three-finger toxins from cobra venom, including cytotoxin 3 from N. kaouthia, cardiotoxin-like basic polypeptide A5 from N. naja (CLBP), and alpha-neurotoxin from N. oxiana venom, was investigated. All toxins failed to i

Cytotoxins (or cardiotoxins, CTs) are small rigid membrane-active proteins of the three-finger toxin (TFT) family. They comprise about 60 amino acid residues, stabilized by four disulphide bridges. CTs, the most abundant proteins in cobra venom are a

Cobra cytotoxins (CTs) belong to the three-fingered protein family. They are classified into S- and P-types, the latter exhibiting higher membrane-perturbing capacity. In this work, we investigated the interaction of CTs with phospholipid bilayers, u
