In winter, spring and summer, the rhizome of wild Elytrzgia repens of Heilongjiang Province was selected to extract the soluble which whole protein and the apoplastic protein, and analyzed by SDS-PAGE. The result indicated that there were two specific polypeptides in two types protein from winter; their relative molecular weight were identified as 52 ku and 26 ku by analyzing software; the apoplastic protein from winter had the ability of modifing the growth of ice crystal which appeared hexagonal in shape observed with the phase-contrast photomicroscope. So the apoplastic protein from winter has the antifreeze characters and the 52 ku protein is more likely the antifreeze protein 展开更多

以黑龙江省野生偃麦草为试验材料,提取冬季偃麦草根茎的非质体蛋白,通过对蛋白质进行SDS-PAGE分析,发现冬季偃麦草非质体蛋白有6条清晰的条带,分子质量为68.0、46.0、39.0、34.0、28.0、23.0ku的蛋白均有可修饰冰晶形态抗冻蛋白存在,其... 以黑龙江省野生偃麦草为试验材料,提取冬季偃麦草根茎的非质体蛋白,通过对蛋白质进行SDS-PAGE分析,发现冬季偃麦草非质体蛋白有6条清晰的条带,分子质量为68.0、46.0、39.0、34.0、28.0、23.0ku的蛋白均有可修饰冰晶形态抗冻蛋白存在,其中分子质量为68.0、46.0、28.0、23.0ku的蛋白具有较高的抗冻活性,34.0ku的蛋白具有较弱的抗冻活性,39.0ku蛋白基本不具抗冻活性;冬季偃麦草非质体蛋白浓度越高,抗冻活性越强。 展开更多
