Crystal Structure of E.coli AMP Nucleosidase complexed with formicin 5'-monophosphate

The structure was published by Zhang, Y., Cottet, S.E., and Ealick, S.E., in 2004 in a paper entitled "Structure of Escherichia coli AMP Nucleosidase Reveals Similarity to Nucleoside Phosphorylases" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.6 Å and deposited in 2004.

The experimental data on which the structure is based was not deposited.

This PDB entry contains multiple copies of the structure of AMP nucleosidase.

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 homohexamers.
