摘要: 分别从中华蜜蜂Apis cerana cerana和意大利蜜蜂Apis mellifera工蜂毒腺中抽提总RNA,通过RT-PCR方法扩增,各得到了蜂毒前溶血肽原蛋白的cDNA,再将扩增产物克隆到pGEM-Teasy载体上,进行测序和序列分析。结果表明,所扩增到的这两个片段长度均为213 bp,均为编码蜂毒前溶血肽原的cDNA,并分别推导出两者所编码的氨基酸序列。经序列比较,中华蜜蜂前溶血肽原与意大利蜜蜂、印度蜜蜂Apis cerana indica前溶血肽原的同源性都为97%。所报道的中华蜜蜂蜂毒前溶血肽原的核苷酸序列的GenBank登录号为AF487907。

Abstract: Two cDNA fragments encoding prepromelittin were amplified by RT-PCR from the total RNA from the venom glands of the worker honeybees, Apis cerana cerana and A. mellifera. The PCR products were ligated into pGEM-Teasy vector. The results of sequencing showed that the ORFs coding for prepromelittin were all 213 bp in length. The amino acid sequence of A. cerana cerana prepromelittin shared 97% homologies with that of A. mellifera prepromelittin and A. cerana indica prepromelittin. The nucleotide sequence reported here was submitted to GenBank with accession no. AF487907.
