Description
Verfahren zur Herstellung der Co-Zymase Die vorliegende Erfindung betrifft eine weitere Ausgestaltung und Verbesserung des Verfahrens des Hauptpatents 5293r9.Process for producing the co-zymase The present invention relates to a further refinement and improvement of the method of the main patent 5293r9.
In diesem Patent ist in Beispiel i die Vorreinigung des dialysierten Hefeextraktes durch Ausfällung der Nebenkörper mittels Bleiacetats und die Entfernung des überschüssigen Bleis aus dem Filtrat durch Fällung mit Schwefelsäure beschrieben, worauf man entweder die Fällung mit Pikrinsäure gleich vornimmt oder die Lösung zunächst mit Quecksilbernitrat behandelt.In this patent, example i is the precleaning of the dialyzed Yeast extract by precipitation of secondary bodies using lead acetate and removal the excess lead from the filtrate described by precipitation with sulfuric acid, whereupon either the precipitation with picric acid is carried out or the solution first treated with mercury nitrate.
Es wurde nun gefunden, daß man, von demselben Material (Hefeextrakt) ausgehend, mit besserer Ausbeute zu einem reineren Endprodukt gelangt, wenn man zwischen die Vorreinigung mit Bleiacetat und die Behandlung mit Quecksilbernitrat bzw. die Fällung mit Pikrinsäure eine an sich bekannte Fällung der Co-Zymase mit Aluminiumsulfat und Ammoniak als basisches Aluminiumsalz einschaltet, woraus die Co-Zymase durch Phosphorsäure wieder in Freiheit gesetzt wird. Beispiel Man dialysiert 11 eingedunsteten Hefeextraktes durch Iiollodiummembran gegen z bis 31 Wasser. Das Dialysat (Außenflüssigkeit) fällt ntan ohne Eindunsten mit einer kalt ge@@ittigten Lösung von Bleiacetat in geringem überschuß. Die dabei entstehende Fällung wird verworfen.It has now been found that, from the same material (yeast extract) starting out, a cleaner end product is obtained with a better yield if one between pre-cleaning with lead acetate and treatment with mercury nitrate or the precipitation with picric acid is a known per se precipitation of the co-zymase Aluminum sulfate and ammonia as the basic aluminum salt turns on, from which the Co-zymase is set free again by phosphoric acid. Example You are dialyzed 11 evaporated yeast extract through iollodium membrane against z to 31 water. That Dialysate (external liquid) falls ntan without evaporation with a cold water Solution of lead acetate in slight excess. The resulting precipitation is discarded.
Das klare Filtrat hiervon wird tropfenweise mit einer z 5 %igen Natriumhydrosulfidlösung und 4n-Schwefelsäure versetzt, bis sich die entstandene Bleisulfidfällung zusammenballt und rasch zu Boden sinkt. Die abfiltrierte Lösung, die nur wenig Schwefelwasserstoffe enthalten soll, wird nach der in Hoppe-Seylers Zeitschrift für physiologische Chemie, Band 133, 1924, Seite 26o ff., beschriebenen Weise auf Co-Zymasegehalt untersucht. Sie wird mit einer konzentrierten Lösung von Aluminiumsulfat versetzt, und zwar mit etwa i g kristallisiertem Salz auf zooo Co-Einheiten. Unter Rühren setzt man dann konzentrierte Ammoni<lklösung zu, bis Phenolphthalein stark gerötet wird. Der Niederschlag wird abzentrifugiert und mit Wasser gewaschen. Er wird dann in Wasser suspendiert und mit Phosphorsäure (z5 ccm etwa 85%iger Säure auf ioog Aluminiumsulfat) versetzt. Man schüttelt z Stunden in der Maschine und saugt ab. Das Filtrat wird mit Bariumacetat und Bariumhydroxyd versetzt, so daß bei etwa neutraler Reaktion kein Niederschlag mehr entsteht. Man saugt ab und wäscht mit etwas Wasser nach. Die so gewonnene Lösung wird in der in Patent 5z9 319 früher beschriebenen Weise mit Quecksilbernitrat u#,w. gefällt.The clear filtrate from this is mixed dropwise with a 5% sodium hydrosulphide solution and 4N sulfuric acid are added until the lead sulfide precipitate that has formed agglomerates and quickly sinks to the ground. The filtered solution containing only a little hydrogen sulfide should contain, according to the in Hoppe-Seylers Zeitschrift für Physiologische Chemie, Volume 133, 1924, page 26o ff., Examined manner described for co-zymase content. It is mixed with a concentrated solution of aluminum sulfate, namely with about 1 g of crystallized salt to zooo Co units. One sets while stirring then add concentrated ammonia solution until phenolphthalein is very reddened. The precipitate is centrifuged off and washed with water. He will then be in Suspended water and with phosphoric acid (z5 ccm about 85% acid on ioog aluminum sulfate) offset. You shake it in the machine for hours and vacuum. The filtrate will mixed with barium acetate and barium hydroxide, so that with an approximately neutral reaction no more precipitation occurs. It is suctioned off and washed with a little water. The solution thus obtained is in the manner described in patent 5z9,319 earlier with mercury nitrate u #, w. pleases.
