'''Three consecutive sheared GA pairs in 5'GGUGGAGGCU/3'PCCAAAGCCG'''
===Three consecutive sheared GA pairs in 5'GGUGGAGGCU/3'PCCAAAGCCG===




==Overview==
<!--
A previous NMR structure of the duplex 5'GGU GGA GGCU/PCCG AAG CCG5' revealed an unusually stable RNA internal loop with three consecutive sheared GA pairs. Here, we report NMR studies of two duplexes, 5'GGU GGA GGCU/PCCA AAG CCG5' (replacing the UG pair with a UA closing pair) and 5'GGU GAA GGCU/PCCG AAG CCG5' (replacing the middle GA pair with an AA pair). An unusually stable loop with three consecutive sheared GA pairs forms in the duplex 5'GGU GGA GGCU/PCCA AAG CCG5'. The structure contrasts with that reported for this loop in the crystal structure of the large ribosomal subunit of Deinococcus radiodurans [Harms, J., Schluenzen, F., Zarivach, R., Bashan, A., Gat, S., Agmon, I., Bartels, H., Franceschi, F., and Yonath, A. (2001) Cell 107, 679-688]. The middle AA pair in the duplex 5'GGU GAA GGCU/PCCG AAG CCG5' rapidly exchanges orientations, resulting in alternative base stacking and pseudosymmetry with exclusively sheared pairs. The U GAA G/G AAG C internal loop is 2.1 kcal/mol less stable than the U GGA G/G AAG C internal loop at 37 degrees C. Structural, energetic, and dynamic consequences upon functional group substitutions within related 3 x 3 and 3 x 6 internal loops are also reported.
The line below this paragraph, {{ABSTRACT_PUBMED_16734425}}, adds the Publication Abstract to the page
(as it appears on PubMed at http://www.pubmed.gov), where 16734425 is the PubMed ID number.
