    BISACCIA F, DEPALMA A, Dierks T, KRAMER R, PALMIERI F. REACTION-MECHANISM OF THE RECONSTITUTED TRICARBOXYLATE CARRIER FROM RAT-LIVER MITOCHONDRIA. BIOCHIMICA ET BIOPHYSICA ACTA. 1993;1142(1-2):139-145.Transport of citrate and malate by the tricarboxylate carrier from rat liver mitochondria has been studied in a reconstituted system. Homologous citrate/citrate antiport and heterologous (electroneutral) citrate/malate antiport was kinetically analyzed. The maximal rates of the two exchange modes did not vary significantly within pH 7.0 to 7.8 which is the optimum pH-range for transport activity. On the other hand, the apparent transport affinity varied considerably within this range. Calculations on the basis of the different pK values for citrate and malate indicate that only H-citrate 2 -and malate 2 -are accepted as transport species by the tricarboxylate carrier. A complete set of half-saturation constants was established for citrate and malate on both the external and the internal side of the membrane. Both the K(m) and V(max) for citrate and malate were independent of the nature of the countersubstrate at the other side of the membrane. Bisubstrate initial velocity analyses of the exchange reaction resulted in a kinetic pattern which is consistent with a sequential antiport mechanism. This type of mechanism implies formation of a ternary complex of the carrier with two substrate molecules before the transport reaction occurs. Thus the tricarboxylate carrier falls into the functional family of mitochondrial carrier proteins showing sequential transport mechanisms

    F. J. L. Kramer : leraar, hoogleraar, archivaris (1850-1928)

    No full text
    Wanneer wij denken aan de Utrechtse leerstoel in de geschiedenis in bet verleden, dan valt ons al direct een aantal bekende namen in: Wijnne, Kernkamp, Geyl. Alle drie waren zij nauw verbonden met zowel de universiteit als met bet Utrechtse culturele leven. F. J. L. Kramer, hoogleraar van 1893-1903, van wie hetzelfde gezegd kan worden, is nu echter vergeten. Volgens de chronologie van de eerder genoemde namen hoort hij tussen Wijnne en Kernkamp. - Overdruk van het Nederlands archievenblad, jg. 87/3 (1983)
