Abstract: Crystals and structures are provided for an eukaryotic RNA polymerase, and an elongation complex containing a eukaryotic RNA polymerase. The structures and structural coordinates are useful in structural homology deduction, in developing and screening agents that affect the activity of eukaryotic RNA polymerase, and in designing modified forms of eukaryotic RNA polymerase. The structure information may be provided in a computer readable form, e.g. as a database of atomic coordinates, or as a three-dimensional model. The structures are useful, for example, in modeling interactions of the enzyme with DNA, RNA, transcription factors, nucleotides, etc. The structures are also used to identify molecules that bind to or otherwise interact with structural elements in the polymerase.
