Although the final result of ammoniainhibition of nitrogenase activity in phototro-phic bacteria is now fairly well understood,there is very little information about theevents leading to the modification of the ironprotein. The aim of this paper was to learnmore about the factors that influence the ironprotein modification system. Nitrogenase activity in Rhodobacter spha-eroides strain 601 was subjected to a rapidswitch-off in response to exogenous ammonia(Fig. 1). However, the inhibition caused byammonia was...

Although the final result of ammoniainhibition of nitrogenase activity in phototro-phic bacteria is now fairly well understood,there is very little information about theevents leading to the modification of the ironprotein. The aim of this paper was to learnmore about the factors that influence the ironprotein modification system. Nitrogenase activity in Rhodobacter spha-eroides strain 601 was subjected to a rapidswitch-off in response to exogenous ammonia(Fig. 1). However, the inhibition caused byammonia was prevented by methionine sul-phoximine, a glutamine synthetase inhibitor(Fig. 2). On the other hand, the inhibitorof glutamine metabolism, 6-diazo-5-oxo-L-norleucine, prolonged the duration of ammoniaswitch-off (Table 1). The inhibition of ni-trogenase activity induced by glutamine ap-pears to be simillar to ammonia switch-off(Fig. 3). It was shown that the inhibition ofnitrogenase activity by ammonia or glutaminein the cells was parallel to the changes ofthe adenylylation state of glutamine synthe-tase. Addition of glutamine to the toluene-treated cells (glutamine synthetase was deade-nylylated) resulted in a decrease of nitrogena.se activity, whereas the correspounding va-lues for the increasing adenylylation of glu-tamine synthetase. However, addition of am-monia to the toluene-treated cells neitherreduced nitrogenase activity nor inducedadenylylation of glutamine synthetase (Table2). From the above results, the possible re-gulatory mechanism of nitrogenase activitywas discussed.

浑球红假单胞菌菌株601具有迅速对外源氨作出“关闭”固氮酶活性的反应。氨对固氮酶的抑制作用,可被谷氨酰胺合成酶(GS)抑制剂MSX所解除。反之,加入Glu代谢抑制剂DON,可延长氨抑制的持续时间。Gln对固氮酶也有抑制作用。在脱腺苷化GS的透性细胞中,加入Gln可抑制固氮酶活性,同时,GS腺苷化状态提高。然而,氨则对透性细胞的固氮酶活性和GS腺苷化状态没有影响。

Objective: The aim of this study was to examine the effect of total parenteral nutrition (TPN) on the glutamine metabolism of the tissues in rats. Methods: The concentration of glutamine was determined by high performance liquid chromatography (HPLC). Results: The results showed that TPN induced marked reduction of glutamine concentration in tissues and blood ( P <0.05 or P <0.01). Prolonged TPN leads to further reduction ( P <0.01). The TPN solution enrinched with glutamine can maintain the glutamine concentration in tissues and improve the glutamine concentration in blood. Conclusions: Prolonged TPN induced obvious reduction of glutamine concentration in tissues and blood. TPN solution enrinched with glutamine can maintain the glutamine metabolism.

AIM: Ammonia(NH4Cl) on glutamine metabolism in cultured astrocytes of three - days - old Wistar rats were investigated in vitro. METHODS: Cultares were treated by NH4Cl with different concentration for various time periods.RESULTS: There was an obvious increase in glutamine synthetase activity and glutamine content in astrocytes under hyperammonemia. These increases were related to both ammonia concentration and time of administration . But little increase was found after ammonia incubation...

AIM: Ammonia(NH4Cl) on glutamine metabolism in cultured astrocytes of three - days - old Wistar rats were investigated in vitro. METHODS: Cultares were treated by NH4Cl with different concentration for various time periods.RESULTS: There was an obvious increase in glutamine synthetase activity and glutamine content in astrocytes under hyperammonemia. These increases were related to both ammonia concentration and time of administration . But little increase was found after ammonia incubation were prolonged to 72 h or ammonia concentration were heightened to 10 mmol/L.CONCLUSIONS: Astrocytes exhibit active changs in glutamine metabolism after beginning of ammonia exposure. However, the glutamine synthetic metabolism may be injured following a prolonged ammonia incubation or increase of ammonia dose, which means that the detoxification ability of astrocyte towards ammonia was reduced.

目的:了解体外培养状态下,NH4+对脑星状胶质细胞谷氨酰胺代谢的影响。方法:将不同浓度NH4Cl加入培养液作用不同时间,分别收集细胞及上清进行测定。结果:NH4+作用后,星状胶质细胞谷氨酰胺合成酶活性增加,细胞内及上清液内谷氨酰胺含量增加,且在一定程度上随着NH4+氨的浓度的增大而增加。然而,当NH4+作用时间达到一定时限(72h)后,酶的活性及细胞内谷氨酰肢的量不再增加,甚至有所下降或减少。结论:星状胶质细胞积极参与NH3(NH3NH4+)的代谢。然而,过高浓度的NH4+作用可影响星状胶质细胞功能,使其对NH4的解毒能力下降。
