Analysis of amino acid content and identification of scorpion toxin ITX protein 蝎毒素ITX氨基酸含量及蛋白质组分分析
Objective: To observe the inhibitory effects of scorpion toxin polypeptide ( STP) extracted from Buthus martensii karsch on the angiogenesis. 目的:探讨从东亚钳蝎蝎毒中分离的蝎毒多肽(STP)对血管形成的抑制作用。
Improvement of baculovirus as insecticide by using a scorpion toxin gene 利用蝎毒基因改良杆状病毒杀虫剂
Analysis of the Genomic Organization of A Novel Scorpion Toxin BmTXK β 一种新的蝎毒素BmTXKβ的基因组结构及分析
Analysis of nucleotide sequence showed that the region encoding mature peptide of BmTXK β was disrupted by an intron with 886 bp, which was different from any other scorpion toxin gene with their introns within the signal peptide coding region. BmTXKβ基因含有一个长度为886bp的内含子,定位于BmTXKβ成熟肽中,与其它蝎毒素基因内含子定位于信号肽的基因结构不同。
Southern hybridization analysis showed that there were two specific hybridization signals, which indicated that scorpion regulated the expression of toxin genes using the mechanism of DNA rearrangement, multicopy or multiple gene family. 杂交结果为蝎毒素基因可能通过DNA重排、多拷贝或多基因家族来调控基因表达提供了证据。
It is interesting to see that a partially purified anti-insect toxin from the Old World scorpion behaved as a β type anti-mammal toxin on mammalian sodium channels. 这种部分纯化的昆虫类毒素对一种哺乳动物细胞钠电流的影响表现出典型的β型哺乳类毒素的性质。
Study on Pellets Preparation of Recombinant Scorpion Toxin Analgesic Peptide 重组蝎毒镇痛肽微丸制剂的研究
Moreover, the characteristics of this intron are different from those of other scorpion toxin genes described previously. 并且,BmTXKβ基因的内含子特征也与其它蝎毒素基因不同。
Scorpion is an animal which preys on mollusk insect. A series of toxin were brought in its body for survival and defense among long term evolution. 蝎是一种以体软昆虫为食的动物,在长期的进化过程中为生存或防卫的需要在其体内产生了一系列毒素蛋白。
Scorpion venom is a biological toxin, because of its wide range of physiological effects closely watched. 蝎毒是一种生物毒素,因其具有广泛的生理学效应而倍受关注。
Scorpion toxin contains various toxic polypeptides with different functions. 蝎毒素中含有多种具有不同功能的活性多肽。
