Legionella pneumophila NTPDase1 N302Y variant crystal form III (closed) in complex with MG UMPPNP

The structure was published by Zebisch, M., Krauss, M., Schaefer, P., Lauble, P., and Straeter, N., in 2013 in a paper entitled "Crystallographic Snapshots Along the Reaction Pathway of Nucleoside Triphosphate Diphosphohydrolases" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.5 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 ECTONUCLEOSIDE TRIPHOSPHATE DIPHOSPHOHYDROLASE I.

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.
