Structure of bovine endothelial nitric oxide synthase heme domain in complex with 3,5-bis(2-(6-amino-4-methylpyridin-2-yl)ethyl)benzonitrile

The structure was published by Huang, H., Li, H., Martasek, P., Roman, L.J., Poulos, T.L., and Silverman, R.B., in 2013 in a paper entitled "Structure-guided design of selective inhibitors of neuronal nitric oxide synthase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.25 Å and deposited in 2013.

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

This PDB entry contains multiple copies of the structure of subunit A.

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 most likely forms homodimers.
