PLA 2 enzymes are commonly found in mammalian tissues as well as arachnid, insect, and snake venom. [2] Venom from bees is largely composed of melittin, which is a stimulant of PLA 2. Due to the increased presence and activity of PLA 2 resulting from a snake or insect bite, arachidonic acid is released from the phospholipid membrane ...
Notexin consists of a single molecule. This molecule is a single-peptide chain of 119 amino acid residues that are cross-linked with 7 disulfide-bridges. [7]X-ray diffraction has been used to determine the crystal structure of notexin and led to the conclusion that notexin belongs to either the P3121 or P3221 space group with lattice parameters a = b = 74.6 Å, c = 49.0 Å with a β of 120⁰.
Given that snake venom contains many biologically active ingredients, some may be useful to treat disease. [42] For instance, phospholipases type A2 (PLA2s) from the Tunisian vipers Cerastes cerastes and Macrovipera lebetina have been found to have antitumor activity. [43] Anticancer activity has been also reported for other compounds in snake ...

A phospholipase is an enzyme that hydrolyzes phospholipids [1] into fatty acids and other lipophilic substances. There are four major classes, termed A, B, C, and D, which are distinguished by the type of reaction which they catalyze: Phospholipase A Phospholipase A 1 – cleaves the sn-1 acyl chain (where sn refers to stereospecific numbering).
Rattlesnake venom is a mixture of five to fifteen enzymes, various metal ions, biogenic amines, lipids, free amino acids, proteins, and polypeptides. More specifically, there are three main families of toxins in rattlesnakes: phospholipases A2 (PLA2s), snake venom metalloproteinases (SVMPs), and snake venom serine proteinases (SVSPs). [49]
Venom metering is the ability of a snake to have neurological control over the amount of venom released into a target during a strike based on situational cues. This ability would prove useful as venom is a limited resource, larger animals are less susceptible to the effects of venom, and various situations require different levels of force.
Snake antivenom is a medication made up of antibodies used to treat snake bites by venomous snakes. [1] It is a type of antivenom . It is a biological product that typically consists of venom neutralizing antibodies derived from a host animal, such as a horse or sheep.
