1rtu Summary



The structure was published by Noguchi, S., Satow, Y., Uchida, T., Sasaki, C., and Matsuzaki, T., in 1995 in a paper entitled "Crystal structure of Ustilago sphaerogena ribonuclease U2 at 1.8 A resolution." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 1995.

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

The PDB entry contains the structure of RIBONUCLEASE U2. This molecule has the UniProt identifier P00654 (RNU2_USTSP)search. The sample contained 114 residues which is 100% of the natural sequence. Out of 114 residues 114 were observed and are deposited in the PDB.

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

The molecule is most likely monomeric.
