Making an emission: T7 RNA polymerase incorporates a series of thiophene‐modified uridine triphosphate (UTP) analogues to generate emissive RNA transcripts. Labeling experiments suggested that the enzyme frequently pauses at the incorporation position and, when incorporation does take place, T7 RNA polymerase fails to elongate the modified oligonucleotides and yields aborted transcripts. TPs=triphosphates
发射:T7 RNA 聚合酶结合一系列噻吩修饰的三磷酸尿苷 (UTP) 类似物来生成发射 RNA 转录本。标记实验表明,该酶经常在掺入位置暂停,当掺入确实发生时,T7 RNA 聚合酶无法延长修饰的寡核苷酸并产生中止的转录本。TP=三磷酸盐。
