(1) Sodium salt of reduced codehydrogenase I has been obtained in good yield as a dry powder from codehydrogenase I by reduction with alcohol and alcohol dehydrogenase. This preparation was stable for at least 5 months when kept dry at -15℃. (2) The properties of the particle-bound codehydrogenase I cytochrome reductase system in heart muscle preparation were found to differ considerably from those of the soluble enzyme as obtained by Mahler et al. Among other things, the affinity for cytochrome c of the particle-bound enzyme is much greater than the soluble enzyme. The Michaelis constant for cytochrome c of the former is only one twelfth of that of the latter.(Fig. 2A). (3) With either oxygen or excess cytochrome c as electron acceptor, it was found that the overall activity, in terms of rate of oxygen consumption or cytochrome c reduction, when both succinate and reduced codehydrogenase I were oxidized simultanously, did not represent the sum of the rates of oxidation when these two substrates were separately oxidized but equalled only the faster of the two separate oxidation rates(Fig. 5, Tables 1, 2). If 2,6-dichlorophenol indophenol was used as the electron acceptor, the overall rate of simultaneous oxidation of these two substrates was found to equal exactly the sum of the rates of separate oxidation(Table 3). (4) When either oxygen or excess cytochrome c was used as the electron acceptor, reduced codehydrogenase I and succinate each inhibited the rate of oxidation of the other(Figs 4, 6 & 7). Evidence has been presented to show that the inhibition of succinate oxidation by reduced codehydrogenase I is not due to the accumulation of oxaloacetate. (5) When malonate was also added to the reaction mixture, succinate no longer produced any inhibition of the oxidation of reduced codehydrogenase I(Fig. 8). (6) It is therefore concluded that in heart muscle preparation both succinate and reduced codehydrogenase I are oxidized by cytochrome c through a common, velocity limiting factor. This is in accordance with the view previously reached by some workers from studies on the action of certain inhibitors. However, it should be noted that in our experiments no agents which might produce any conceivable change in the colloidal structure of the enzyme system has been employed. (7) It should be emphasized that our results clearly show that great caution must be exercised in drawing conslusion on the role an enzyme might play in a complex enzyme system from studies of the properties of a solubilized enzyme. (8) It is believed that the competition of two enzyme systems for a common linking factor as demonstrated in this report has provided a new method for studies on the mutual relations of two or more enzyme systems.

(1) Cytochrome c containing 0.43% iron has been obtained from beef, pig or horse heart muscles by direct adsorption of the neutralized trichloroacetic acid extracts of heart muscle on the cation exchanger"synthetic zeolite" followed by elution with 3.84 M ammonium sulfate and precipitation with 20% trichloroacetic acid. This provides a simple method for large-scale preparation of pure cytochrome c. (2) The ratio of optical densities at 550 mμ(reduced) and 278 mμ of 0.43% iron cytochrome c varies, with its degree of reduction, from 1.13 to 1.26. The average ratio of our preparations is 1.23. (3) The absorption spectra(230-600 mμ) of oxidized and reduced cytochrome c have been measured. The molecular extinction coefficient at 550 mμ of oxidized, 0.43% iron, cytochrome c is 0.80×10~4. This value differs considerably from that reported in the literature. (4) Some enzymic properties of cytochrome c containing 0.43% iron are compared with those of a preparation containing 0.34% iron and are found to be identical. Both can be converted into''endogenous" cytochrome c. (5) Whether pure cytochrome c contains more than 0.43% iron has been discussed. It seems that no convincing evidence has been presented to show that cytochrome c preparations with iron content higher than 0.43% as obtained by some workers do not contain a small amount of iron-rich impurity.

(一)用陽離子交换劑(synthetic zeolite)直接吸附高等動物心肌抽提液一次,並用3.84M硫酸銨作洗脫劑,即可製得含鐵量0.43%的細胞色素c。因此提供了一個大量製備純細胞色素c的簡單方法。 (二)含鐵量0.43%的細胞色素c,它的550mμ和278mμ光密度的比值,視產品的還原程度而定,其範圍從1.13到1.26,我們所製得的產品,其比值在1.23左右。 (三)我們测量了氧化及還原的細胞色素c(含鐵0.43%)從230mμ到600mμ的吸收光譜,並發現和前人所報告的略有不同。氧化細胞色素c在550mμ的消光係數為0.80×10~4,此值與文獻上的數值相差很多。 (四)我們比較了含鐵量0.43%的細胞色素c和含鐵量0.34%的細胞色素c的一些性質,證明他們是相同的;並且兩者都可以變成“內源”細胞色素c。 (五)我們認為現有的實驗證據不足以說明純細胞色素c的含鐵量大於0.43%。

Although the occurence of a coenzyme I-independant, particle-bound α-glycerophosphate dehydrogenase in skeletal muscle of higher animals has long been recognized, little is known about its relation to the cytochrome system. Green has found that it is linked to cytochrome c but details of the electron transporting pathway has remained obscure. This problem has now been studied using the method of simultaneous action of two or more enzyme systems as described previously. Enzyme preparation obtained from thoroughly washed rabbit muscle mince has been employed in the present investigation. It has been found that in the presence of the rabbit muscle enzyme preparation, succinate and α-glycerophosphate each interferes with the rate of oxidation of the other when they are oxidized simultaneously. The inhibition of α-glycerophosphate oxidase by succinate can be reversed by the addition of pyrophosphate, a powerful inhibitor of succinic dehydrogenase. With cytochrome c as electron acceptor, the overall rate of simultaneous oxidation of α-glycerophosphate, succinate and reduced coenzyme I (CoIH) does not represent the sum of the rates of their separate oxidation, but corresponds only to the highest of the three rates, i.e. the rate of oxidation of CoIH. It is, therefore, believed that the α-glycerophosphate-, succinate- and CoIH-cytochrome c reductase systems have a common, velocity limiting electron carrier which is most probably the linking factor first proposed by Slater. In agreement with this conclusion, the α-glycerophosphate oxidase of rabbit muscle preparation has been found to be sensitive to the action of 2,3-dimercaptopropanol. Using 2,6-dichlorophenolindophenol, as acceptor, the overall rate of the simultaneous oxidation of succinate and α-glycerophosphate equals exacdy to the sum of the rates of their separate oxidation. Similar results have also been obtained even in presence of phenylurethane, which markedly inhibits the activity of succinic dehydrogenase and does not affect the activity of α-glycerophosphate dehydrogenase. These facts suggest that cytochrome b is not involved in the oxidation of α-glycerophosphate in rabbit muscle preparation. The pathway of hydrogen or electron transfer of the particulate α-glycerophosphate oxidase system may, therefore, be represented as follow: (See also Fig. 4)

(一) 在經徹底冲洗的兔骨骼肌製劑中,[L-α]甘油磷酸和琥珀酸的氧化彼此干涉。琥珀酸對[L-α]甘油磷酸氧化的抑制作用能因加入抑制琥珀酸脫氫的焦磷酸而解除。 (二) 當用細胞色素c作受體時[L-α]甘油磷酸,還原輔I和琥珀酸三者同時氧化時總氧化速度僅相當其中氧化速度最高者即還原輔I單獨氧化的速度。[L-α]甘油磷酸氧化系也因[2,3]二氫硫基丙醇的處理而失效。 (三) 當用[2,6]二氯酚靛酚作受體時[L-α]甘油磷酸和琥珀酸同時氧化時速度完全等於二底料單獨氧化時速度的和。[L-α]甘油磷酸的氧化不受苯代氨甲酸乙酯的影響。 (四) 本文結果說明[L-α]甘油磷酸的氧化不通過細胞色素b而通過中間因子和細胞色素c連接。
