magnetosome 中文意思是什麼

magnetosome 解釋
磁體
  1. Two magnetosome deletion mutants were constructed by conjugative transposon mutagensis and the application of this genetic system. the two magnetosome deletion mutants were named as nm4 and nm21 respectively

    並利用此體系，通過接合轉座誘變技術，獲得了2個磁小體缺失突變株： nm4 、 nm21 。
  2. The protein encoded by orf1 show strong homology with cation efflux family protein from geobacter sulfurreducens pca [ identities = 65 / 272 ( 23 % ) ], and contains mmt1 - like putative conserved domains kog1485, mmt1 contains conserved domains kog1485 is mitochondrial fe2 + transporter ( cation diffusion facilitator superfamily ). so it can be considered that the protein encoded by o rf1 is fe2 + transporter involved in magnetosome biosynthesis in magnetospirillum gryphiswaldense msr - 1

    經同源比較和保守性結構域分析，推測orf1編碼的蛋白具有fe ~ （ 2 + ）轉運功能，在磁小體合成過程中將細胞質中fe ~ （ 2 + ）轉運到磁小體囊泡中，合成磁小體的同時去除fe ~ （ 2 + ）對細胞的毒害作用。
  3. The tn5 inserted in the orf4. it was demonstrated that this fragment was related to magnetosome biosynthesis by experiment of functional complement. the orf4 encodes a protein which is homologous to the atpase from magnetospirillum magnetotacticum ms - 1 and contains a rec domain which has a chey - homologous receiver domain

    該片段由6個orf組成， tn5插入在3621bp - 3622bp間，位於orf4起始密碼子下游的84bp處， orf4因tn5插入失活，通過功能互補實驗證明該片段與磁小體合成相關。
  4. It indicated that the magnetosome deleted phenotype w as caused by tn5 insertion

    Southern雜交驗證磁小體缺失突變確為tn5插入所致。
  5. Progress in genomic study and biochemical formation of magnetosome chains in magnetotactic bacteria

    趨磁細菌基因組和磁小體成鏈機制研究進展
  6. The genetic analysis of the mechanism of magnetosome biosynthesis in magnetospirillum gryphiswaldense msr - 1 has been hampered by the lack of an appropriate genetic manipulation system. here reported on the establishment of a genetic manipulation system that can be used more readily than that of the others for magnetospirillum

    格瑞菲斯瓦爾德磁螺菌（ magnetospirillumgryphiswaldensemsr - 1 ）為趨磁螺菌屬（ magnetospirillum ）的模式菌株，能夠在胞內合成大小約為42am的磁小體（ magnetosome ） 。
  7. Research progress and application prospect of magnetosome

    細菌磁小體形成機制和應用研究進展
  8. It was demonstrated that this fragment was related to magnetosome biosynthesis by experiment of functional complement

    功能互補實驗證明其與磁小體合成相關。
  9. The sequences flanking tn5 in magnetosome deleted mutant nm4 was cloned by anchored pcr, and was used as tag to extend the 5 ' and 3 ' terminal sequences of the target dna fragment by anchored pcr constinuously

    以tn5為標簽，用錨定pcr法克隆出突變株nm4的tn5側翼序列。並以此側翼序列為標簽繼續用錨定pcr法向兩邊延伸，克隆出一個5045bp的dna片段。
  10. This domain receives the signal from the sensor partner in bacterial two - component systems. these results indicated that the protein of the orf4 works as atpase function involved in the synthesis of magnetosome or takes part in the signal transduction relate to the promotion of magnetosome biosynthesis

    通過對orf4編碼蛋白同源比較和功能分析，推測orf4編碼蛋白可能的功能有兩種：具atpase活性，在磁小體合成過程中為鐵轉運提供能量；或參與磁小體合成啟動過程中的信號轉導。
