Zum aktiven Na+, K+‐Transport durch die Membran tierischer Zellen

Abstract: Der Transport von N a + aus der Zelle und von K + in die Zelle entgegen einem Konzentrationsgradienten wird durch eine (Na' +-K+)-aktivierte ATPase katalysiert. Wie die Kationen die Zellmembran durchdringen, ist bisher ungeklart. Beim Studium der ATP-Hydrolyse durch das Enzym fand sich eine Na+-abhangige Phosphorylierung des Enzymproteins : zusatzlich scheint sich seine Konformation zu andern. Bei der K+-abhangigen Hydrolyse des enzyrngebundenen Phosphats wird wahrscheinlich die Energie fir den Transport der K… Show more

“…The activity of many enzymes is known to be modified by various alkali and alkaline earth cations (see [1][2][3][4][5] ). Though these ions only are able to exert relatively weak coordinative forces, the complex formation apparently enables them to keep enzyme proteins in specific biologically active conformations.…”
