Crystal structure of P450NOR complexed with 3-pyridinealdehyde adenine dinucleotide

The structure was published by Oshima, R., Fushinobu, S., Su, F., Zhang, L., Takaya, N., and Shoun, H., in 2004 in a paper entitled "Structural evidence for direct hydride transfer from NADH to cytochrome P450nor" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.8 Å and deposited in 2004.

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

The PDB entry contains the structure of CYTOCHROME P450 55A1. This molecule has the UniProt identifier P23295 (NOR_FUSOX)search. The sample contained 403 residues which is 100% of the natural sequence. Out of 403 residues 399 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.
