  • Title: Cytochrome c takes on plasmalogen catabolism.
    Author: Goldfine H.
    Journal: J Biol Chem; 2018 Jun 01; 293(22):8710-8711. PubMed ID: 29858391.
    Abstract:
    Plasmalogens-phospholipids containing a characteristic vinyl ether group-are precursors of lipids important for cellular signaling such as arachidonic acid. Plasmalogen catabolism involves cleavage of the vinyl ether bond, but the identity of the corresponding enzyme that cleaves the sn-1 vinyl ether bond was unknown. New research shows that cytochrome c, with some help from another lipid, catalyzes the oxidative cleavage of this bond. This discovery, and the subsequent mechanistic dissection, provides exciting new directions for lipid signaling research.
