Catalytic importance of a protonated adenosine in the hairpin ribozyme active site. [PDF]
The hairpin ribozyme accelerates the rate of phosphodiester transfer reactions by at least 5 orders of magnitude. To achieve this rate enhancement, the active site forms via a substrate helix docking event that constrains the scissile phosphate linkage ...

QM/MM studies of hairpin ribozyme self-cleavage suggest the feasibility of multiple competing reaction mechanisms. [PDF]
The hairpin ribozyme is a prominent member of small ribozymes since it does not require metal ions to achieve catalysis. Guanine 8 (G8) and adenine 38 (A38) have been identified as key participants in self-cleavage and -ligation.

A comparative survey of the influence of small self-cleaving ribozymes on gene expression in human cell culture [PDF]
Self-cleaving ribozymes are versatile tools for synthetic biologists when it comes to controlling gene expression. Up to date, 12 different classes are known, and over the past decades more and more details about their structure, cleavage mechanisms and ...

A triplex ribozyme expression system based on a single hairpin ribozyme. [PDF]
Triplex ribozyme (RZ) configurations allow for the individual activity of trans-acting RZs in multiple expression cassettes (multiplex), thereby increasing target cleavage relative to conventionally expressed RZs. Although hairpin RZs have been advantageously compared to hammerhead RZs, their longer size and structural features complicated triplex ...

Critical domain interactions for type A RNase P RNA catalysis with and without the specificity domain. [PDF]
The natural trans-acting ribozyme RNase P RNA (RPR) is composed of two domains in which the catalytic (C-) domain mediates cleavage of various substrates. The C-domain alone, after removal of the second specificity (S-) domain, catalyzes this reaction as
