(1)When etiolated wheat seedlings were illuminated, chlorophyll appeared immediately, but no photophosphorylation activity could be found. After about 3 hrs. of greening, photophosphorylation activity began to appear and its rate, calculated on chlorophyll basis, increased up to 7—8 hrs., after which it became more or less constant, while the chlorophyll content of the chloroplasts continued to rise.(2)The capacity of ATP formation(per nag. chlorophyll)by cyclic photophosphorylation was much higher than that...

(1)When etiolated wheat seedlings were illuminated, chlorophyll appeared immediately, but no photophosphorylation activity could be found. After about 3 hrs. of greening, photophosphorylation activity began to appear and its rate, calculated on chlorophyll basis, increased up to 7—8 hrs., after which it became more or less constant, while the chlorophyll content of the chloroplasts continued to rise.(2)The capacity of ATP formation(per nag. chlorophyll)by cyclic photophosphorylation was much higher than that by noncyclic photophosphorylation at the early stages of greening, but their difference became smaller as the greening goes on.When the capacity of ATP formation by cyclic photophosphorylation was compared with the O_2 evolving power by noncyclic photophosphorylation, no such difference in ratio during greening was observed. This fact indicates, that the low capacity of noncyclic photophosphorylation is mainly due to its lower degree of coupling, and not to the involvement of a O_2 evolving step which might develop slower. The development of the ATP formation capacity of the oxidative photophosphorylation with DCPIPH_2 as hydrogen donor during greening behaved similarly to that of noncyclic photophosphorylation, and also lagged behind that of cyclic photophosphorylation. This fact further confirms the conclusion that the cause of delayed development of ATP formation capacity by noncyclic photophosphorylation is not connected with the O_2 evolving step.(3)The light intensity required to saturate the photophosphorylation and Hillreaction activities of the greening wheat-seedling chloroplasts was found to be similar to that of fully green control. At the beginning of the development of the photophosphorylation capacity, it had a strong"light intensity effect", i.e. the slowing down of the rate of electron transport at low light intensity resulted in an uncoupling of the phosphorylating mechanism. This phenomenon may have some relation to the extraordinarily low capacity of ATP formation of noncyclic photophosphorylation at the early stage of greening.(4)During greening of etiolated wheat seedlings, the appearance of CO_2 assimilation was approximately simultaneous to that of the photophosphorylation capacity, but the activity calculated on chlorophyll basis, seemed to reach a maximum much earlier.

(1)黄化小麦幼苗初变绿时,光合磷酸化活力之发生远较叶绿素的生成为迟。在实验条件下,照光变绿3小时后,才可测得光合磷酸化活力,且其按叶绿素为基础计算的活力随照光变绿时间的增加而增加,至照光变绿7—8小时后,叶绿体上叶绿素含量尚在继续增加,但光合磷酸化活力则趋向恒定。(2)在黄化幼苗变绿初期,测得的循环光合磷酸化ATP形成能力较非循环光合磷酸化ATP形成能力高得多,以后较接近;但将循环光合磷酸化之ATP形成能力与非循环光合磷酸化之放氧能力相比较,则其比例在不同时期相差不大。这说明,在变绿初期非循环光合磷酸化之ATP形成能力特别小的原因,主要是由于当时它的偶联程度特别低,并不是因为它较循环光合磷酸化多牵涉到放氧等步骤,而这些步骤可能发生得较晚所致。以DCPIPH_2作氢供体的氧化光合磷酸化活力的最初增长情况与以Fe(CN)_6~≡作氢受体的非循环光合磷酸化ATP形成能力的增长情况一样,均比以PMS促进的循环光合磷酸化活力增长时间为晚,这结果也有助于证明非循环光合磷酸化ATP形成能力增长较晚的原因与它牵涉到放氧步骤无关。(3)使黄化变绿幼苗光合磷酸化、希尔反应活力达到饱和所需的光强度与绿苗所需的相仿。变...

The content of iron protein, being the more oxygen-sensitive component of nitrogenase, was found to be much lower than the Mo-Fe protein in the extracts prepared from sonicated Azotobacter vinelandii cells. The nitrogen-fixing activity of the extracts remained practically unchanged on adding partially purified MoFe protein, while it was increased many times on adding partially purified iron protein (Fig. 1).The nitrogen-fixing activity of A. vinelandii extracts as was shown earlier in the literature, might be...

The content of iron protein, being the more oxygen-sensitive component of nitrogenase, was found to be much lower than the Mo-Fe protein in the extracts prepared from sonicated Azotobacter vinelandii cells. The nitrogen-fixing activity of the extracts remained practically unchanged on adding partially purified MoFe protein, while it was increased many times on adding partially purified iron protein (Fig. 1).The nitrogen-fixing activity of A. vinelandii extracts as was shown earlier in the literature, might be recovered in pellets obtained by centrifugation. It was discovered that an enhanced activity of the extracts due to added iron protein was also obtained under the same treatment (Tab. 1) and was more oxygen resistant than that of the free iron protein (Fig. 2). Thus it seemed probable that the added iron protein might combine with certain constituents of the extracts to form a complex, which could be separated by centrifugation and was more resistant to oxygen.Mg~(++) was a necessary factor to prevent the nitrogen-fixing activity of the extracts from being inactivated by oxygen. The extracts lost their activity completely as soon as they passed through Sephadex G-25 column in air, but maintained their full activity under the same treatment, if 0.01 M MgCl_2 was included in both the equilibrating and eluting buffers (Tab. 2). Addition of suitable amount of Mg~(++) to the cell suspension before sonication not only enhanced the activity of the extracts obtained, but also made it still more resistant to oxygen inactivation (Fig. 3 and 4).

超声破碎得到的棕色固氮菌提取液中,铁蛋白严重缺乏。外加部分纯化的铁蛋白可以使提取液的固氮活性成倍增加。外加的铁蛋白与提取液中某些成份结合,可以经高速离心分离,其抗氧能力随之大为提高。提取液中固氮活性的抗氧能力有赖于Mg~(++)的存在,在有氧条件下提取液通过Sephadex G-25柱后立即失活,但如果在平衡和洗脱缓冲液中补以0.01M MgCl_2,固氮活性几乎可完整保存。菌体破碎时,外加适量Mg~(++),不但可以提高提取液的固氮活性,而且抗氧能力还能进一步提高。
