Crystal structure of nitrophorin 2 aqua complex

A publication describing this structure is not available. The depositing authors are Weichsel, A.search; Berry, R.E.search; Walker, F.A.search; Montfort, W.R.search

This crystal structure was determined using X-ray diffraction at a resolution of 1.7 Å and deposited in 2005.

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

The PDB entry contains the structure of Nitrophorin 2. This molecule has the UniProt identifier Q26241 (NP2_RHOPR)search. The sample contained 180 residues which is 100% of the natural sequence. Out of 180 residues 180 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.
