A Molecular Identity Crisis - a 'Ribozyme Without RNA'

(PhysOrg.com) -- Not all enzymes that are assumed to require an RNA component in order to function do actually contain RNA. This surprising discovery was made during a project supported by the Austrian Science Fund FWF that focussed on the enzyme RNase P. Contrary to accepted scientific theory, the project team from Vienna has long believed that certain forms of RNase P do not contain any RNA. They have now succeeded in proving their point through a series of sophisticated experiments, the results of which are being published today in the journal Cell.
