| Abstract: | Abstract The active site of the self splicing intron in the T4 nrdB RNA has been modelled on a graphics workstation on the basis of the suggested 3D arrangement of the Tetrahymena IVS1. This structure was then subjected to energy minimization and molecular dynamics simulation to relax tensions. The cofactor guanosine was docked to a proposed2 binding site where it was found to fit well. |
