摘要 在序列分析的基础上,使用PCR技术构建了藻蓝蛋白裂合酶CpcE/CpcF基因的缺失突变体:cpcE(42~276)、cpcE(1~274)、cpcE(1~272)、cpcF(1~160)、cpcF(10~213).突变体基因克隆至表达载体pET 30a(+)后,利用体外重组实验对表达蛋白的酶活性进行了研究.揭示了缺失区域在酶催化过程中的作用. On the basis of sequence analysis, deletion mutants of phycocyanin lyase CpcE/CpcF in Mastigocladus laminosus were constructed: cpcE(42-276), cpcE(1-274), cpcE(1-272), cpcF(1-160), cpcF(10-213). Gene of the deletion mutants was then cloned into expression vector pET 30a(+). The activities of the expressed proteins were studied through the in vitro reconstitution test, which showed the function of deleted domain in the enzyme catalysis.
