WebWe have found that both catalytic elements, renamed GIR1 and GIR2, are group I ribozymes, but with differing functionality. GIR2 carries out the several reactions … WebAug 31, 2001 · Abstract. Orbital steering is invoked to explain how the three-dimensional structure of a small self-cleaving RNA, the hammerhead ribozyme, both prevents and enhances RNA autocatalysis. Within the conserved catalytic core of the ribozyme, the position of the 2' oxygen atom of the G8 ribose is observed to be aligned almost perfectly … Webthe template (T) ribozyme can be 50–70 nucleotides in length, autocatalysis is possible, and cross catalysis (i.e., A + B / T0 coupled with A0 + B0 / T) can result in the ultimate … is minehut cross platform
