  • Title: Activity of phospholipase A2 in the inner membrane of rat-liver mitochondria.
    Author: Zurini M, Hugentobler G, Gazzotti P.
    Journal: Eur J Biochem; 1981 Oct; 119(3):517-21. PubMed ID: 7308197.
    Abstract:
    The inner membrane of rat liver mitochondria contains a highly active phospholipase A2 which has alkaline pH optimum and requires Ca2+ in the micromolar range. The phospholipase is particularly active on the endogenous phosphatidylethanolamine and release relatively high amounts of docosahexanoic acid. The phospholipase A2 of mitochondria or mitoplasts is not dependent on calmodulin. Using fluorescamine-labelled mitoplasts there are indications that the enzyme is localized on both sides of the inner membrane.
