  • Title: Mitochondria from the lamprey (Lampetra fluviatilis). Oxidative phosphorylation and related processes.
    Author: Savina MV, Wroniszewska A, Wojtczak L.
    Journal: Acta Biochim Pol; 1975; 22(3):229-38. PubMed ID: 1179911.
    Abstract:
    1. High efficiency of oxidative phosphorylation and a good respiratory control in liver, heart and somatic muscle mitochondria of the lamprey (Lampetra fluviatilis) were observed when the particles were isolated in a complex sucrose medium containing EDTA, heparin and nicotinamide. The coupling properties of these mitochondria were further improved by including serum albumin in the incubation medium. 2. The content of total adenine nucleotides in lamprey mitochondria was between 4 and 6 nmoles/mg protein. The translocation of these nucleotides across mitochondrial membrane was stimulated by serum albumin. 3. Lamprey mitochondrial phospholipids contain a large proportion (64-72%) of polyunsaturated fatty acids. 4. Electron micrographs of mitochondria from lamprey liver, heart and somatic muscle are presented.
