Phylogenetic and genetic evidence for base-triples in the catalytic domain of group I introns

open access: closedNature, 1990
Understanding the mechanisms by which ribozymes catalyse chemical reactions requires a detailed knowledge of their structure. The secondary structure of the group I introns has been confirmed by comparison of over 70 published sequences, by chemical protection studies, and by genetic experiments involving compensatory mutations.

Minimum secondary structure requirements for catalytic activity of a self-splicing group I intron

open access: closedBiochemistry, 1990
We have completed a comprehensive deletion analysis of the Tetrahymena ribozyme in order to define the minimum secondary structure requirements for phosphoester transfer activity of a self-splicing group I intron. A total of 299 nucleotides were removed in a piecewise fashion, leaving a catalytic core of 114 nucleotides that form 7 base-paired ...

A 3′ splice site-binding sequence in the catalytic core of a group I intron

open access: closedNature, 1990
Ribozymes use specific RNA-RNA interactions for substrate binding and active-site formation. Self-splicing group I introns have approximately 70 nucleotides constituting the core, a region containing sequences and structures indispensable for catalytic function.

Footprinting the Sites of Interaction of Antibiotics with Catalytic Group I Intron RNA

open access: closedScience, 1993
Aminoglycoside inhibitors of translation have been shown previously to inhibit in vitro self-splicing by group I introns. Chemical probing of the phage T4-derived sunY intron shows that neomycin, streptomycin, and related antibiotics protected the N-7 position of G96, a universally conserved guanine in the binding site for the guanosine ...
