Secretory Phospholipases A2 in Plants [PDF]
Les phospholipases sécrétées (sPLA2) dans les plantes sont un groupe croissant d'enzymes qui catalysent l'hydrolyse des glycérophospholipides sn-2 en lysophospholipides et en acides gras libres. À ce jour, environ 20 sPLA2 seulement ont été rapportés à partir de plantes.

Human phospholipases A2: a functional and evolutionary analysis [PDF]
Phospholipases A2 (PLA2) are capable of hydrolyzing the sn-2 position of glycerophospholipids to release fatty acids and lysophospholipids. The PLA2 superfamily enzymes are widespread and present in most mammalian cells and tissues, regulating metabolism,

Short Linear Motifs Characterizing Snake Venom and Mammalian Phospholipases A2 [PDF]
Snake venom phospholipases A2 (PLA2s) have sequences and structures very similar to those of mammalian group I and II secretory PLA2s, but they possess many toxic properties, ranging from the inhibition of coagulation to the blockage of nerve ...

Black-necked spitting cobra (Naja nigricollis) phospholipases A2 may cause Trypanosoma brucei death by blocking endocytosis through the flagellar pocket [PDF]
African trypanosomes, such as Trypanosoma brucei, are flagellated protozoa which proliferate in mammals and cause a variety of diseases in people and animals. In a mammalian host, the external face of the African trypanosome plasma membrane is covered by

Secreted Phospholipases A2 in Hereditary Angioedema With C1-Inhibitor Deficiency [PDF]
BackgroundHereditary angioedema (HAE) caused by deficiency (type I) or dysfunction (type II) of the C1 inhibitor protein (C1-INH-HAE) is a disabling, potentially fatal condition characterized by recurrent episodes of swelling. We have recently found that

Inhibition of nicotinic acetylcholine receptors, a novel facet in the pleiotropic activities of snake venom phospholipases A2. [PDF]
Phospholipases A2 represent the most abundant family of snake venom proteins. They manifest an array of biological activities, which is constantly expanding. We have recently shown that a protein bitanarin, isolated from the venom of the puff adder Bitis

Pancreatic and snake venom presynaptically active phospholipases A2 inhibit nicotinic acetylcholine receptors. [PDF]
Phospholipases A2 (PLA2s) are enzymes found throughout the animal kingdom. They hydrolyze phospholipids in the sn-2 position producing lysophospholipids and unsaturated fatty acids, agents that can damage membranes.

Calcium-independent phospholipases A2 and their roles in biological processes and diseases [PDF]
Among the family of phospholipases A2 (PLA2s) are the Ca2+-independent PLA2s (iPLA2s) and they are designated group VI iPLA2s. In relation to secretory and cytosolic PLA2s, the iPLA2s are more recently described and details of their expression and roles ...
