nitrogenase,英語單詞,主要用作名詞,作名詞時譯為“[生化] 固氮酶”。
固氮酶是一種能夠將氮分子還原成氨的酶。固氮酶是由兩種蛋白質組成的:一種含有鐵,叫做鐵蛋白,另一種含鐵和鉬mo3+,稱為鉬鐵蛋白。鉬鐵蛋白中含有7個鐵,9個硫,1個鉬,1箇中心碳。基本信息 1960年,人們獲得了無細胞的固氮酶提取液,在此基礎上,Carnahan和Mortenson等成功地實現了體外固氮。Bullen和LeComte...
固氮酶組分2 固氮酶組分2,一種鐵硫蛋白。接受來自鐵氧還蛋白的電子傳遞給固氮酶組分1,伴隨著ATP水解為ADP。分子質量50~60 kDa,由2個單體組成,含4個鐵原子,十幾個硫原子。
固氮酶組分1 固氮酶組分1是一種化學物質。
釩固氮酶,是一種在固氮細菌身上發現的酵素,它是第二種固氮方法,當主要的金屬鉬固氮酵素無法運作時。 在自然的氮循環中,釩固氮酶是非常重要的構成要素,它將空氣中的氮氣轉換成氨,使原本無法被植物利用的氮氣變成有用的。最近美國的學者發現,當一氧化物存在時就會減少釩固氮酶,並產生乙烯、乙烷、丙烷。生物上...
固氮酶活性 固氮酶活性是1998年公布的土壤學名詞。定義 固氮酶的作用能力及其強弱。出處 《土壤學名詞》。
對於固氮微生物來說,固氮基因(nif)操縱和調節固氮酶(Nitrogenase)的合成,從而使固氮微生物具有固氮作用。如果將固氮基因進行人工轉移,就可能獲得具有固氮作用的新物種。在這一領域人們已進行了大量的研究,進展顯著。固氮基因已經能夠在原核生物界細菌之間轉移,例如,已能將肺炎克氏桿菌的固氮基因轉移到大腸桿菌中去。
固氮反應的必要條件:(1)能量(ATP);(2)還原力[H]極其載體:NAD(P)H2,由鐵氧還蛋白(Fd),黃素氧還蛋白(Fld)傳遞至鐵蛋白。(3)固氮酶(nitrogenase)。固氮酶通常是由兩個亞基蛋白成分組成的,組分I:“固氮酶”,又稱鉬鐵蛋白(MF)或鉬鐵氧還蛋白(MoFd)組分II:“固氮酶還原酶”,又稱鐵蛋白...
10.避免戶外的灰塵進入缸中,特別是風大的期間一定要關閉窗戶,都市中如果空氣污染、懸浮物較嚴重,可考慮設定空氣濾清器。鐵離子是紅泥藻中的 nitrogenase的電子傳送者,缸中鐵質的多寡與紅泥藻族群數有極大的關係,且鐵離子比磷酸更具關鍵性。而灰塵中的鐵會增加缸中的鐵離子含量達到其需求量以上。重症處理 第1天...
