查询词典 specificity

The purified recombinant enzyme had optimal reaction conditions at pH 5.0 and 80 °C, was stable between pH 4.0 and pH 6.0. The enzyme had residual activity of 60% at 95 °C for 6 h at pH 5.0, thus has considerable potential in industrial applications. The specific activities of the enzyme to salicin, p-Nitrophenyl β-D-glucopyranoside, p-nitrophenyl β-D-xylopyranoside and p-nitrophenyl α-D-glucopyranoside were: 57500 U/mg, 1632 U/mg, 109 U/mg, and 39 U/mg, respectively, the specificity of salicin was the highest, p-nitrophenyl β-D-glucopyranoside followed, no activities to xylan and arabinofuranoside.

重组 Tm-SIGlA 的酶学性质研究表明：该酶最适作用温度和最适作用 pH 分别为80 ℃和 pH 5.0；在 pH 4.0-6.0 之间酶活性稳定，95 ℃保温 6 h 残留活性为 60%，具有非常高的热稳定性；在所测定的底物中，该酶对水杨苷、对硝基苯酚-β-D-葡萄糖苷(p-Nitrophenyl β-D-glucopyranoside)、对硝基苯酚-β-D-木糖苷(p-Nitrophenyl β-D-xylopyranoside)和对硝基苯酚-α-D-葡萄糖苷(p-Nitrophenyl α-D-glucopyranoside)的比酶活分别为：57500 U/mg、1632 U/mg、109 U/mg 和39 U/mg，作用水杨苷的专一性最强，其次为对硝基苯酚-β-D-葡萄糖苷，没有检测到对木聚糖和阿拉伯糖苷的活性。
