2bsx Summary



The structure was published by Schnick, C., Robien, M.A., Brzozowski, A.M., et al., Hol, W.G.J., Brannigan, J.A., and Wilkinson, A.J., in 2005 in a paper entitled "Structures of Plasmodium Falciparum Purine Nucleoside Phosphorylase Complexed with Sulfate and its Natural Substrate Inosine" (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 2.0 Å and deposited in 2005.

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

The PDB entry contains the structure of PURINE NUCLEOSIDE PHOSPHORYLASE. This molecule has the UniProt identifier Q8I3X4 (Q8I3X4_PLAF7)search. The sample contained 253 residues which is 100% of the natural sequence. Out of 253 residues 241 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 most likely forms homohexamers.
