Structural Characteristics and Evolution of the Protobothrops elegans Pancreatic Phospholipase A2 Gene in Contrast with Those of Protobothrops Genus Venom Phospholipase A2 Genes.

The article presents a study which compares the structural characteristics and evolution of the Protobothrops elegans pancreatic phospholipase (PePancPL) A₂ gene with Protobothrops genus venom phospholipase A₂ genes. The study uses inverted polymerase chain reaction (PRC) technique, nucleotide sequence, and phylogenetic analysis to determine the difference between the two genes. Results show that venom PLA₂ are dissimilar to Protobothrops genus (Crotalinae).
