Hammerhead ribozyme kinetics [PDF]
RNA, 1998 The hammerhead ribozyme is a small RNA motif that self cleaves at a specific phosphodiester bond to produce 2′,3′ cyclic phosphate and 5′ hydroxyl termini (Hutchins et al., 1986; Forster & Symons, 1987a). The secondary structure of the hammerhead consists of three helices of arbitrary sequence and length (designated I, II, and III) that intersect at 15

Advanced Functional Materials, Volume 36, Issue 5, 15 January 2026.Many known diseases arise from dysregulated gene expression, and differentially expressed genes can serve as biomarkers to distinguish diseased cells from healthy tissues. In this study, reconfigurable nucleic acid nanoparticles (recNANPs) are introduced that can detect overexpressed cancer biomarkers and subsequently release RNAi inducers to silence ...
