E.coli numbering 已有1人參與
|
| 親們,有誰知道E.coli numbering是什么意思,在看放線菌中的MAR1,說這類放線菌的E.coli numbering的Nucleotide position(16S rRNA)的有些堿基比較特殊,可是看測序結(jié)果時(shí)沒有發(fā)現(xiàn)這些位置堿基的特殊性,E.coli numbering是不是不是提交的序列中的信息?求助,非常感謝。 |

看下面 區(qū)別Photorhabdus和Xenorhabdus兩個屬的DNA堿基差異在383和503的位置(E.coli numbering),所有的Xenorhabdus為G和A,而所有的Photorhabdus為A和C。 http://cdmd.cnki.com.cn/Article/CDMD-11920-2004091330.htm Figure 5. Structure of conserved residues within the 23S rRNA active site from the H.marismortui 50S subunit crystal structure (2). The A2450+C2063 wobble pair (E.coli numbering) is shown in orange, A2451 is shown in blue, G2061 and G2447 are shown in green and C2501 is in yellow. The N1 of A2451 that reacts with DMS is shown as an enlarged sphere. The hydrogen bonds between A2450+C2063 that are likely to be disrupted by mutation to a G?U pair are shown in red. This includes interactions within the A2450+C2063-C2501 triple, as well as the G2061-A2451-G2447 triple stacked above it. 原文鏈接:http://www.100md.com/html/DirDu/2007/02/17/37/12/79.htm |
