It is a distinct structure to the Magnesium responsive RNA element. The Ykok leader was originally described as a conserved sequence with potential riboswitch function found upstream of the ''B. subtilis'' ykoK gene and genes with related functions in other bacteria. Examples of the conserved M-box RNA structure occur upstream of each of the three major families of Mg2+ transporters (CorA, MgtE and MgtA/MgtB) in various bacterial species. The molecular structure of the M-box example upstream of the ''B. subtilis'' ykoK gene includes six bound Mg2+ ions. Biochemical studies indicate that this M-Box RNA compacts in the presence of Mg2+ and other divalent ions. This folding process appears to disrupt an antiterminator structure, and thereby allow a transcription terminator structure to form. As expected from this model, ''B. subtilis'' cells repress expression of a downstream reporter gene when grown in the presence of Mg2+. Therefore, the M-box appears to function as a genetic "off" switch that is important for maintaining Mg2+ homeostasis in bacteria. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「YkoK leader」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
