Enzymatic footprinting
WebNov 10, 2024 · For footprinting based on enzymatic reactions, the treatment of an end-labeled RNA with enzymatic reagents yields RNA fragments of different sizes. Analysis of the patterns of end-labeled RNA fragments via denaturing gel electrophoresis or sequencing finally allows conclusions on the RNA structure and mapping of protein-binding sites. WebChemical and enzymatic footprinting experiments, such as shape (selective 2'-hydroxyl acylation analyzed by primer extension), yield important information about RNA …

WebWhile the earliest enzymatic footprinting experiments were designed to determine the sequence specificity of a DNA binding protein ( Galas and Schmitz, 1978 ), footprinting techniques have evolved to provide detailed structural insight into nucleic acids and nucleic acid–protein complexes ( Dhavan et al. 2003; Revzin, 1993 ). WebIn chemical and enzymatic footprinting experiments the GAL4 fragment protects guanines in base pairs 6-7 from methylation. Phosphate backbone to protein interaction: The two recognition modules lie in the major groove separated by about one-and-one half turns of the DNA helix ( larger distance compared to proteins of the helix-turn-helix motif ...
