title: Role of Mg2+ in the ribozyme system.
abstract: Recently, several kinds of catalytic activities have been identified from L-19 IVS RNA or 'ribozyme'. In the catalytic process of ribozyme, Mg2+ is required. We investigated the role of Mg2+ by molecular orbital calculation. Based on the results of the calculation, a model for the self-splicing reaction was constructed.
