Description générale

Phospholipase D is a phospholipid hydrolyzing enzyme and an important component of receptor-mediated signal transduction responses and regulated secretion.
Phospholipase D (PLD) is abundantly found in the eukaryotes and prokaryotes. It is present in all mammalian cells. In mammals, PLD is initiated by various hormones, neurotransmitters, growth factors and cytokines.

Application

Phospholipase D from Arachis hypogaea (peanut) has been used in the preparation of lipase enzyme solution. It has also been used to determine its influence on human neutrophil respiratory function.
Research has shown ADP-ribosylation factor regulation of phospholipase D is important in the release of nascent secretory vesicles from the trans-Golgi network. It has also been used in a study to investigate stimulation of Na+-Ca2+ exchange activity in canine cardiac sarcolemmal vesicals.

Actions biochimiques/physiologiques

Hydrolyzes the phosphate bonds of phospholipids and sphingomyelin to give the corresponding phosphatidic acid.
Phospholipase D is involved in conferring drought susceptibility in peanuts, which increases the risk of aflatoxin contamination.
Phospholipase D (PLD) modulates cell growth, secretion and the actin cytoskeleton.

Preharvest aflatoxin contamination has been identified by the peanut industry as a serious issue in food safety and human health because of the carcinogenic toxicity. Drought stress is the most important environmental factor exacerbating Aspergillus infection and aflatoxin contamination in

Treatment of canine cardiac sarcolemmal vesicles with phospholipase D resulted in a large stimulation (up to 400%) of Na+-Ca2+ exchange activity. The phospholipase D treatment decreased the apparent Km (Ca2+) for the initial rate of Nai+-dependent Ca2+ uptake from 18.2
