1.00 A Crystal Structure Of V36A/D129A/L130A Mutant of Nitrophorin 4 From Rhodnius Prolixus Complexed With Nitric Oxide at pH 5.6

A publication describing this structure is not available. The depositing authors are Amoia, A.M.search

This crystal structure was determined using X-ray diffraction at a resolution of 1.0 Å and deposited in 2007.

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

The PDB entry contains the structure of Nitrophorin-4. This molecule has the UniProt identifier Q94734 (NP4_RHOPR)search. The sample contained 184 residues which is 100% of the natural sequence. Out of 184 residues 184 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.
