The results showed that expression plasmid pET22b-lysB was constructed successfully. Highly purified recombination protein was obtained 33.2 mg from 1 L LB culture medium. A screening for His-LysB activity on esterase and lipase substrates confirmed the lipolytic activity. With p-nitrophenyl butyrate as substrate, the thermal stability of the enzyme was poor when the temperature was above 30oC. The enzyme exhibited higher stability at pH 5.0–9.5. The optimum temperature and pH for the lipolytic activity of His-LysB were 23oC and 7.5 respectively. Under the optimum conditions, the specific activity of His-LysB was 1.3 U/mg. Zn2+, Cu2+, Mg2+, Mn2+and phenylmethane sulfonyl fruoride severely inhibited the lipolytic activity of His-LysB.

结果表明:成功构建了pET22b-lysB表达载体,并从1 L的LB培养物中获得了33.2 mg高纯度重组蛋白;His-LysB具有分解脂肪的能力,属于脂肪酶;生物化学特性分析表明:丁酸对硝基苯为水解底物,His-Lys热稳定性不佳,30℃以下比较稳定,随着温度的升高,稳定性逐渐降低;该蛋白具有较高的pH值适应性,pH 5.0~9.5范围内稳定性较高;在23℃和pH 7.5时酶活力最高,其比酶活为1.3 U/mg;金属离子Zn2+、Cu2+、Mg2+、Mn2+和苯甲基磺酰氟抑制剂对酶活具有强烈的抑制作用。
