Crystal Structure Of 3',5"-Aminoglycoside Phosphotransferase Type IIIa ADP Neomycin B Complex

The structure was published by Fong, D.H. and Berghuis, A.M., in 2002 in a paper entitled "Substrate promiscuity of an aminoglycoside antibiotic resistance enzyme via target mimicry." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.7 Å and deposited in 2005.

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

The PDB entry contains the structure of Aminoglycoside 3'-phosphotransferase. This molecule has the UniProt identifier P0A3Y5 (KKA3_ENTFL)search. The sample contained 263 residues which is < 90% of the natural sequence. Out of 263 residues 263 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.
