WebThe HDV ribozyme is located in the genome of the Hepatitis delta virus, a human pathogen that can superinfect patients already infected with hepatitis B. Its structure consists of five helices forming a double pseudoknot, which makes it extremely stable to heat and denaturing agents. This ribozyme is located on both the sense and the antisense ...

http://websites.umich.edu/~rnapeopl/WalterLabPub/Jeong(03).pdf WebThe hepatitis delta virus (HDV) ribozyme is a non-coding RNA found in the hepatitis delta virus that is necessary for viral replication and is the only known human virus that utilizes ribozyme activity to infect its host. The ribozyme acts to process the RNA transcripts to unit lengths in a self-cleavage reaction during replication of the hepatitis delta virus, which is …
WebA shorter HDV sequence that cleaves itself efficiently would be advantageous. Here we show that a recently discovered, small HDV ribozyme is a good alternative to the previously used HDV ribozyme. The new HDV ribozyme is more efficient in some sequence contexts, and less efficient in other sequence contexts than the previously used HDV ribozyme ...
