In the present study, solution structure of an RNA fragment having UUCGA pentaloop was analyzed by NMR spectroscopy. It was found that the UUCG tetraloop is formed and the adenosine residue at the 3' side of the tetraloop is bulged out. The characteristic motif of the loop-bulge structure has also been found in other RNAs including CUUGU and CUGGC pentaloops. Along with the recently found T-hairpin structure with a UUUGAUU loop, in which UUUGA pentaloop and UU bulge are formed, the loop-bulge structures can be categorized as an RNA motif and it may be called as the integrated structure loop, I-loop.
