WebDec 1, 2024 · Introduction. A β-hairpin is a protein supersecondary structure that consists of two antiparallel β-strands connected by a β-turn or a short loop. 1 A typical example of β-hairpin is found in the C2H2 zinc-finger, a DNA-binding domain in which a β-hairpin and a short helix are kept together by coordinating a zinc ion with two Cys thiols from the β … WebHigh GC content and/or secondary structures: Denature secondary structures by heating RNA at 65°C for ~5 min, then chilling rapidly on ice, prior to reverse transcription. Minimize the formation of hairpin sequences by performing reverse transcription at a higher temperature (e.g., 50°C).
WebAbstract. The effects of a T3S mutation on the stability of a 3:5 beta-hairpin forming peptide (YITNSNGTWT) are investigated. Molecular dynamics simulations in explicit water indicate that the wild-type peptide forms a stable hairpin whereas the T3S mutant does not, in agreement with the experimental data.
