title: A ligase ribozyme obtained from a structured pool.
abstract: Here we report the in vitro selection experiment employed to construct a catalytic site on a self-folding RNA. To practice the selection, the sequence of 30 nucleotides was located in close proximity of the putative reaction site in a derivative of a naturally occurring RNA with a well known 3D structure. The acquired catalytic RNA retained the starting 3D structure and was successfully reconstructed according to its modular structure.
