title: Nucleic acid enzymes.
abstract: Last year provided new structural data, particularly for the group I intron and the Hepatitis delta ribozymes, that were essential for a better understanding of the RNA structure/function relationship. The role of metal ions in catalysis of ribozyme action still remains elusive, however. In vitro selection has continued to be a rich source for obtaining data on new nucleic acid enzyme activities.
