The conformation of adenovirus VAI-RNA in solution
Department of Microbiology, The Biomedical Center Box 581, S-751 23 Uppsala, Sweden
Received July 13, 1981. The secondary structure of an adenovirus associated low molecular weight RNA (VAI-RNA) has been studied by partial digestion with T1-RNase and S1-endonuclease followed by T1-fingerprint analysis. The empirical secondary structure has been compared with two computer generated models based on mimimal free energy of the structure. The results suggest that VAI-RNA in solution has a compact structure with a free energy of around -60 kcal with two stems and four bulge regions. The implication of this structure for the function of VAI-RNA is discussed.
