VS ribozyme

From Wikipedia, the free encyclopedia

The Varkud satellite (VS) ribozyme is an RNA enzyme that carries out the cleavage of a phosphodiester bond [1].

[edit] Structure

The VS ribozyme is composed of 5 helices that form an H shape (helices II to VI). The first helix (I) contains the substrate cleavage site in the stem-loop.

[edit] Species Distribution

The VS ribozyme has only been found in DNA of Neurospora mitochondria.
