enzyme fractionation 解釋
酶的分級分離
  • enzyme : n. 【化學】酶。 digestive enzyme 消化酶。 induced enzyme 誘導酶。
  • fractionation : n. 【化學】分餾(法);分層分離,分級分離,份化。
  1. 6 - phosphogluconate dehydrogenase ( 6 - pgadase, ec 1. 1. 1. 44 ) was isolated by homogenate, ammunium sulfate fractionation, deae - sepharose chromatography, blue - sepharose affinity chromatography and gel filtration with sephadex g - 200 from bacillus subtilis, and some properties of the enzyme had been studied. a 113. 8 - fold purification was obtained with a 8. 2 % yield. the purified enzyme moved as a single electrophoretic band in page

    將枯草芽孢桿菌超聲波破壁后的粗提取物進行分段鹽析、 deae - sepharose陰離子交換柱層析, blue - sepharosecl - 6b特異結合柱層析和sephadexg - 200凝膠過濾等純化步驟,得到聚丙烯酰胺凝膠電泳為單一蛋白區帶,比活為1 . 46u mg的酶制劑。
  2. - acetolactate decarboxylase are widely found among bacterial strains but not in other groups of organisms. the enzyme has been demonstrated to be effective for removal of acetolactate and widely used in beer product. in this paper, - acetolactate decarboxylase from bacillus subtilis was purifed to homogeneity from cell extract by ammonium sulfate - fractionation, heat treatment, deae - sepharose fast flow column chromatography

    本文對來源於枯草芽孢桿菌( bacillussubtilis ) 3226 - 5的-乙酰乳酸脫羧酶經硫酸銨分級沉澱、熱處理、 deae - sepharosefastflow離子交換柱層析等分離純化步驟,得到sds - paeg電泳純,通過n末端氨基酸序列分析驗證酶蛋白的純度。
  3. Without ammonium sulphate fractionation and dialysis, the supernatant of crude extract was directly loaded on deae - sepharose cl 6b column equilibrated by phosphate buffer ( 50mmol / l, ph7. 8 ), and the enzyme fraction was not absorbed on the column but impurities were absorbed

    粗酶液無需硫酸銨沉澱及透析,即可引入磷酸緩沖液( 50mmol l , ph7 . 8 )預平衡的deae - sepharosecl6b柱,上柱後用平衡緩沖液洗至基線穩定。 afpga不被吸附而直接流出。
  4. The enzyme was purified from cell extract by ammonium sulfate fractionation ( 30 % - 80 % saturation ) and consecutive column chromatography using deae - cellulose and sephadex g - 100. the sod activity for purified enzyme could reach 4966 iu / mg proteins, and the molecular weight of the sod was about 20 kda which determined by sds - page electrophoresis. when the non - denaturing polyacrylamide gel stained with substrate for sod in the present of 0. 2mmol / l kcn or 0. 5 mmol / l h2o2, the active band was still showed at the same position, which indicated the sod could not be inhibited by the treatments with kcn or h2o2 and it was the mn sod

    通過sds一聚丙烯酸胺凝膠電泳可知該sod酶的分子量約為20kda .在非變性聚丙烯酞胺凝膠( pagb )電泳后,在凝膠son顯色反應液中加入0 . 2耐01 / lkcn或0 . 5inmol / lh202 ,凝膠sod顯色反應后在原來的sod酶部位仍然含有sod活性帶,這表明利用kcn和h20 :處理並不能抑制500的活性,該sod屬于mn一sod 。
