The unstable part of the apical stem of duck hepatitis B virus epsilon shows enhanced base pair opening but not pico- to nanosecond dynamics and is essential for reverse transcriptase binding.

8 Nov 2009 Hepatitis B virus (HBV) replication starts with binding of reverse transcriptase (RT) to the apical stem-loop region of epsilon, a conserved element of the RNA pregenome. For duck HBV, an in vitro replication system has provided molecular details of ... Read more...

Single-molecule analysis of protein-free U2-U6 snRNAs.

30 Oct 2009 Spliceosomes catalyze the maturation of precursor mRNAs in organisms ranging from yeast to humans. Their catalytic core comprises three small nuclear RNAs (U2, U5 and U6) involved in substrate positioning and catalysis. It has been postulated, but ... Read more...

From consensus structure prediction to RNA gene finding.

30 Oct 2009 Reliable structure prediction is a prerequisite for most types of bioinformatical analysis of RNA. Since the accuracy of structure prediction from single sequences is limited, one often resorts to computing the consensus structure for a set of ... Read more...
