摘要:
用不同试剂从西红柿种子提取甘露聚糖外切酶，结果表明甘露聚糖外切酶只能被含高盐的缓冲液（0.1mol/L Hepes+500mmol/L NaCl，pH7.0）提取出来，单独的低盐缓冲液（0.1mol/L Hepes，pH7.0）或用非盐洗涤剂代替高盐则不能提取该酶.通过基因枪将甘露聚糖外切酶和GFP融合蛋白转化洋葱表皮细胞，发现转化了甘露聚糖外切酶和GFP融合蛋白的洋葱表皮细胞壁上有荧光，表明甘露聚糖外切酶可能定位在细胞壁上.
Abstract:
β-mannosidase was extracted from tomato seeds with different buffers. The results show that the β-mannosidase activity is present in high salt buffer (0.1mo l /L Hepes + 500 mmol /L NaCl, pH 7.0), but not in low salt buffer. Non-ionic detergents can not replace the effect of high salt By introducing the β -mannosidase-GFP fusion protein construct into onion epidermal cells via gene gun bombardment, fluorescence can be observed in the β-mannosidase-GFP transformed onion cells. This indicat that β-mannosidase might be localized in the cell wall.
