X-ray crystal structure of Archaeoglobus fulgidus Rio1 bound to (2E)-N-benzyl-2-cyano-3-(pyridine-4-yl)acrylamide (WP1086)

The structure was published by Mielecki, M., Krawiec, K., Kiburu, I., et al., Priebe, W., Lesyng, B., and Laronde-Leblanc, N., in 2013 in a paper entitled "Development of novel molecular probes of the Rio1 atypical protein kinase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.095 Å and deposited in 2013.

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

The PDB entry contains the structure of RIO-type serine/threonine-protein kinase Rio1. This molecule has the UniProt identifier O28471 (RIO1_ARCFU)search. The sample contained 258 residues which is 100% of the natural sequence. Out of 258 residues 250 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.
