摘要:
以山桃叶片为材料提取RNA,反转录后得到cDNA,通过PCR扩增得到1个山桃醇腈酶基因全长编码序列,并命名为PdHNL1PdHNL1的开放阅读框为1 737 bp,预测编码蛋白包含539个氨基酸。氨基酸序列比对结果表明,PdHNL1编码的蛋白具有葡萄糖甲醇胆碱氧化还原酶的序列特征,与黑樱桃醇腈酶PsHNL4蛋白相似度为92%,与桃假定的HNL蛋白相似度为77%。通过将PdHNL1基因连接到原核表达载体pET28(a)上,并转化大肠杆菌BL21 (DE3)后,成功构建了原核表达重组菌株。SDS-PAGE电泳结果显示,重组蛋白受IPTG诱导表达,分子量大小约为62.4 ku,与已报道的其他蔷薇科植物的醇腈酶蛋白大小基本一致。
