Die Steuerung der Arginasewirkung durch Sauerstoff. 9. Mitteilung zur Kenntnis der Arginase.

Abstract: In der 7. Mitteilung 1 ) dieser Reihe wurde gezeigt, daß wäßrige Arginaselösungen durch Sauerstoff in ihrer Wirkung geschädigt werden. Wird die Durchströmung der Losung mit Sauerstoff so durchgeführt, daß Inaktivierung durch Schaumhildung vermieden wird, so zeigen Enzymlösungen, die mit Sauerstoff behandelt wurden, eine deutliche Schädigung gegenüber solchen, durch die während der Dauer der Spaltung Stickstoff oder Wasserstoff durchgeleitet wurde, oder die einfach in oberflächlicher Berührung mit Luft standen.… Show more

“…between arginase activation and the oxidation-reduction potential, for the establishment of which oxygen [Waldschmidt-Leitz, McDonald et al, 1933] or hydrogen [Edlbacher et al, 1933] is necessary, is in harmony with the experimental findings and accounts for the activations observed with the abovementioned compounds.…”

“…These newly demonstrated activators however possess in common the property of forming reversible redox systems. The hypothesis of a connection between arginase activation and the oxidation-reduction potential, for the establishment of which oxygen [Waldschmidt-Leitz, McDonald et al, 1933] or hydrogen [Edlbacher et al, 1933] is necessary, is in harmony with the experimental findings and accounts for the activations observed with the abovementioned compounds.Investigations reported by various writers during the past year have shown that in general these oxidations and reductions are regulated by reversible redox systems, which in the presence of available oxygen or hydrogen show variable potentials. Of significance to the investigation is the fact that the potential is determined not by the total amount of the system present but only by the ratio of the reduced to the oxidised phase.…”
