fe protein造句

• 2 . proceedings of the reseaches on the novel nitrogenase mnfe protein and crfe protein several new batches of mnfe protein and crfe protein were prepared . their substrate reduction activities have been determined by the complementation with uw45 fe protein
  新型固氮酶mnfe蛋白和crfe蛋白的特性与结晶研究在已有的工作基础上，分离纯化了几批mnfe蛋白和crfe蛋白，并用部分纯的ugh fe蛋白进行活性互补，分别测定了mnfe蛋白和crfe蛋白的底物还原活性。
• Pcr amplification using 2 degenerate primers for nitrogenase fe protein gene was performed with chromosomal dna isolated from the 29 isolates . the result suggested that a nifh amplicon of 323 nucleotides was detected in 7 isolates and the 7 isolates are c4 c5 g1 g2 , w5 t1 and t7 . these pcr amplified fragments were cloned , and sequenced
  首先利用芽孢杆菌中芽孢的抗热性将土壤溶液在100沸水中煮10 - 15分钟，然后用选择性无氮培养基进行初筛得到29株菌落形态不同的菌株；接着用固氮酶结构基因nifh的特异性引物对这29株菌进行pcr扩增，结果表明其中7个菌株具有nifh基因，这7个菌株的编号依次为： c4 、 c5 、 g1 、 g2 、 w5 、 t1和t7 。
• When complemented with fe protein , the nifb mofe protein had hardly any ft - reducing activity , but could be significantly reactivated by femoco extracted from op mofe protein to a high proton - reducing activity , which was very close to the highest value of c2h2 - reducing activity report ed previously in other laboratorys
  此粗提物可为用nmf抽提的opmofe蛋白的femoco激活，所得fe蛋白具有与opfe蛋白相似的互补活性，可使opmofe的比活性达到2192nmolc _ 2h _ 2 min mg蛋白。
