Crystal structure of RNA 3'-terminal phosphate cyclase, an ubiquitous enzyme with unusual topology

The structure was published by Palm, G.J., Billy, E., Filipowicz, W., and Wlodawer, A., in 2000 in a paper entitled "Crystal Structure of RNA 3'-Terminal Phosphate Cyclase, a Ubiquitous Enzyme with Unusual Topology" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.1 Å and deposited in 1999.

The experimental data on which the structure is based was also deposited.

This PDB entry contains multiple copies of the structure of RNA 3'-TERMINAL PHOSPHATE CYCLASE.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.
