By using the similar separation and purification methods, a nifh and a nife mofe protein were obtained from azotobacter vinelandii mutants dj54 and dj35. the results of the complement activity experiments showed that a nifh mofe could be activated by femoco
從棕色固氮菌突變種dj _ （ 54 ）中得到了nifhmofe蛋白；並參與了棕色固氮菌突變種dj _ （ 35 ）的nifemofe蛋白的分離純化，所用方法與nifb ~ - mofe蛋白的分離純化相似。Under suitable conditions, dark brown short rhombohedron crystals could be obtained from nifb mofe protein. both of the longest sides of the biggest crystal were o. lmm. the possibility and time of the formation of crystals, and number, size, quality, and shape of crystals obviously depended not only on the kinds and concentrations of the components in the crystalline solution, but also on the methods for crystallization and technical bias, etc
對nifb ~ - mofe蛋白的結晶及晶體生長進行了的研究，初步探討了結晶溶液各組分的種類和濃度、結晶方法和實驗操作等與能否出現晶體及晶體的數目、大小、質量、形狀和出晶時間等的相互關系。The preliminary results showed that the crystals could be formed from the nifb " mofe protein
初步結果表明，這種晶體可能就是nifb ~ - mofe蛋白的晶體。( 4 ) h2 evolution by mofe protein with a - gln194 and citrate substitutions was inhibited by co at 32 % inhibition rate, comparing to 71 % of that for nifv - mofe protein
Co對nifv ~ - mofe蛋白放氫的最大抑制率為71 ， - gln ~ （ 194 ）和檸檬酸雙重替換使的co抑制固氮酶放氫的最大抑制率下降到31 。Comparison of substrate - reduction properties of these altered mofe proteins with wt and nifv - mofe proteins showed that : ( 1 ) only the a - gln194 substitution did not affect the total electron to proton reduction and notably double altered mofe protein with substitution of citrate and a - lys190 only retained very poor proton reduction activity. ( 2 ) a - gln194 substitution made a more direct effect on n2 reduction then other two substitutions
四個突變體固氮酶、野生型和nifv ~ -固氮酶的mofe蛋白的底物還原特性比較表明： （ 1 ） - gln ~ （ 194 ）替換不影響固氮酶還原質子時的總電子流；尤其引人注意的是，含有- lys ~ （ 190 ）和檸檬酸雙重替換的mofe蛋白幾乎完全失去了質子還原的能力。分享友人
