title: Three dimensional model for the 16S ribosomal RNA in the Escherichia coli ribosome.
abstract: Molecular modeling has been performed to help correct and refine an approximate three dimensional structure for Eschericia coli 16S rRNA that originated as hand-built wire model. The wire model was built to accommodate the base pairs in 16S rRNA (1), mRNA.16S rRNA interactions (2,3), rRNA.ribosomal protein interactions (see 4), ribosomal protein-ribosomal protein distances (5), intramolecular RNA-RNA UV-crosslinks (6,7) and site-directed mutagenesis experiments (8). In the computer model, individual base-paired regions were constructed separately and then were installed into the expected locations to produce the entire structure. We describe here the considerations, steps and results of this refinement process.
