GNRA tetraloops, found in high frequency in natural RNAs, make loop-receptor interactions, stabilizing the tertiary structure of Group I introns, a class of small RNAs. Analyzing 230 Group I introns, to study the distribution and sequence pattern of the GNRA tetraloops, we suggest that these features reflect the ancestral nature of these catalytic molecules… CONTINUE READING
