monitoring equilibrium changes in rna structure by 'peroxidative' and 'oxidative' hydroxyl radical footprinting

RNA分子は、生物学において重要な役割を果たしている。遺伝情報を伝達することに加えて、RNAはレギュレータ、バインダーや触媒などの特定の生物学的役割を果たすユニークな立体構造に折りたたまれることができる。三次接触の形成についての情報は、RNA分子の機能を理解することが不可欠です。ヒドロキシルラジカル（•OH）は、その高い反応性と小さなサイズのため、核酸の構造のユニークなプローブである。1フットのプローブとして使用する場合は、ヒドロキシルラジカルがDNAを1とを有するRNA 2のホスホジエステルバックボーンの溶媒接触可能表面をマッピング一塩基の解像度と同じくらい素晴らしい。ヒドロキシルラジカルフットプリンティングはDNA -タンパク質1とRNA -タンパク質複合体で、例えば、分子間の接触面内のヌクレオチドを識別するために使用することができます。平衡3と4の遷移運動は、solutiの関数としてヒドロキシルラジカルフットプリンティングを行うことによって決定することができます変数または時間で、それぞれ。フットプリントの主な特徴は、プローブにその限られた暴露（例えば、&quot;シングルヒット動力学&quot;）ポリマーの各ヌクレオチドの均一サンプリングの結果です。5 このビデオの記事では、我々は、RNAサンプルの調製およびMg（II）を介したフォールディング等温線の測定を説明するために、 テトラヒメナのリボザイムのP4 - P6のドメインを使用してください。我々は、H 2 O 2（我々はこの&quot;過酸化&quot;プロトコルと呼ぶ）と自然に溶存O 2を使用している貴重な、しかし広く知られていない、別のを（我々が呼ぶこの&quot;必要とするよく知られているヒドロキシルラジカルフットプリンティングプロトコルの使用を説明し酸化&#39;プロトコル）。データの削減、変換および分析手順の概要が提示される。
